Valid Bracket Sequence

Given a string containing only (, ), [, ], {, and }, determine whether every opener is closed by the matching type in the correct order.

Practice focusThe empty string is valid. A closing bracket with no pending opener is invalid, as is any opener left at the end. Target O(n) time and O(n) worst-case space. Staged follow-ups 1. Ignore brackets inside quoted strings while respecting escape characters. 2. Report the location and expected token for the first mismatch. 3. Validate a stream incrementally across chunk boundaries.

Fixed-Window Token Limiter

Implement a per-key limiter with one shared token limit and fixed window length. Commands are:

Practice focus- ("ALLOW", key, cost, timestamp) : accept if the key's usage plus cost does not exceed the limit; a rejected request consumes nothing. - ("RESET", key, timestamp) : clear that key's usage in the fixed window containing timestamp . The window containing time t starts at (t // window) window . Costs are non-negative integers; zero is allowed. Preserve input order. Return one result per command, using booleans for ALLOW and a consistent acknowledgment for RESET .…

Seat row

During a timed test, mark seats as taken and report the first free seat.

Practice focusOnline assessment. A row of seats is numbered from 1. Implement take, which marks a free seat as taken and fails if that seat is already taken. Implement first free, which returns the lowest numbered free seat, or reports that the row is full. Then the test adds a second row and asks you to search the first row before the second. Write both functions and one example of a full row.

Two name lists

On a phone screen, merge two sorted name lists and keep one copy of a shared name.

Practice focusPhone screen. You are given two lists of names. Each list is already in alphabetical order. Return one list in that order. A name that appears in both lists appears once. An empty list stays empty. Then the interviewer adds a name that appears twice in the first list and asks you to keep one. State that rule, then write the function.

Build an Unbiased Randomness Adapter

Turn an unknown biased bit source into balanced choices, a sampled load estimate, and isolated concurrent batches.

Practice focusYou receive a hardware source raw bit() that independently returns 0 or 1 with one stable but unknown probability of returning 1 . The probability is strictly between zero and one, and no other random source is available. Implement the following four functions. Requirements 1. Extract balanced bits Read the raw source in fresh pairs. Discard pairs whose values match. For the first pair whose values differ, return its first value. A scripted source raises EOFError when exhausted; let that exception propagate, including for a partial pair.…

First position of a target in a sorted array

Given a nondecreasing array and a target value, report where the target first appears, or -1 when it is missing. A logarithmic search is expected, even though the same value may occur many times.

Practice focusRequirements - Line one is the element count n . Line two holds the n space-separated integers in nondecreasing order, and is empty when n is 0. Line three is the target. - Return the smallest zero-based index holding the target, as a decimal string with no padding. - Return -1 when the array is empty or the target never appears. - Repeated values are expected, so an ordinary equality hit is not enough; after a match keep searching to the left while remembering the best index seen. - Keep the running time logarithmic in n .…

Per-function exclusive runtime from a call log

A single thread records start and end events for nested function calls. For each function id, work out how many time units it actually spent running, excluding the units spent inside calls it made.

Practice focusRequirements - Line one is the number of functions; ids run from 0 to count - 1 and every id appears at least once. Line two is the number of event lines. - Each remaining line is <id :<start|end :<timestamp with integer fields. Events are chronological and properly nested on one thread. - An end timestamp is inclusive: the unit at that timestamp belongs to the call that is ending, so it contributes timestamp - previous + 1 units. - When a call begins on top of a running call, credit the units since the previous boundary to the caller.…

Maximum haul from non-adjacent houses

Each house on a street holds a known amount of money, and robbing two neighboring houses on the same night trips the alarm. Choose houses with no two adjacent to collect the largest possible total.

Practice focusRequirements - Line one is the house count. Line two lists that many non-negative integer amounts, separated by spaces. - Adjacency is positional, so choosing the house at index i rules out only i - 1 and i + 1 . - Return the best total as a decimal string with no separators. - A single house contributes its own amount, and a zero amount is a legal choice, so a street of zeros answers 0 . - Every house is a candidate; skipping a house is never required just because it is small. - run case passes case["stdin"] to solve .…

Values unique to the first list

Two Python-style lists arrive as literal assignments. Collect every value that belongs to the first list but not the second, keeping the first list's order.

Practice focusRequirements - The input holds two assignment statements, one per entry: list1 = [...] followed by list2 = [...] . Both lists contain integers and may be empty. - The statements may be separated by a real newline or by a literal two-character \n escape; split on either form. - Return the kept values in their original list1 order. - Membership in list2 is decided by value, not by count or position, so a single occurrence there removes every matching occurrence in list1 .…

Longest run of distinct characters

Given a string, measure the longest contiguous stretch in which no character repeats. Report only the length of that stretch.

Practice focusRequirements - The input is a single string, and the trailing newline is not part of the payload. - A stretch must be contiguous, and every character inside it must be distinct. - Return the length as a decimal string, not the slice itself and not its starting position. - Characters compare exactly, so an uppercase and a lowercase letter are different characters. - A string whose characters all match answers 1 , and the longest stretch may sit anywhere in the payload.…

Peak simultaneous bookings

Given a list of half-open time ranges, report the largest number of ranges that are active at the same instant.

Each following line holds start end , two integers with start strictly less than end . - Treat a booking as occupying the half-open interval [start, end) . - Because the interval is half-open, a booking that ends at a time does not conflict with one that starts at that same time. - Return the peak number of concurrent bookings as a decimal string. - An empty booking list returns "0" . - run case(case: dict) forwards case["stdin"] to solve .…

Merge three ordered lists without repeats

Combine three nondecreasing integer lists into one nondecreasing list in which every distinct value appears once, then print it as a single space-separated line.

Practice focusRequirements - The input has exactly three lines. Each line starts with a count k followed by k nondecreasing integers. - The merged result must stay sorted and must contain each distinct value exactly once. - Values may be negative, zero, or positive. Duplicates can appear within one line and across lines. - Print the distinct values in one line separated by single spaces, with no leading or trailing space. - If all three lists are empty, return an empty string. - run case(case: dict) forwards case["stdin"] to solve .…

Next arrangement in lexicographic order

The next arrangement is the smallest arrangement strictly greater than the current one. - Duplicate values are allowed. - If the current arrangement is already the largest, return the smallest arrangement, with values in ascending order. - Print the resulting list in one space-separated line, keeping the same length and the same multiset of values. - run case(case: dict) forwards case["stdin"] to solve .…

Count distinct values in an ordered list

Given a nondecreasing integer sequence, report how many different values it contains.

Practice focusRequirements - The input is one line of space-separated integers in nondecreasing order. - Equal values are therefore adjacent, and the sequence may contain negative values. - Return the number of distinct values as a decimal string. - You do not need to print or return the compacted sequence itself. - run case(case: dict) forwards case["stdin"] to solve . - Do not append a trailing newline to the returned string; return the value exactly once.

Zero rows and columns around each zero

Given a matrix, set every cell in a row or column that contains a zero to zero, deciding which rows and columns to clear from the original values rather than from the partially rewritten matrix.

Practice focusRequirements - Line 1 is rows cols . The next rows lines each hold cols integers. - For every cell that is 0 in the original matrix, its entire row and entire column become 0 . - Decide all affected rows and columns before writing any zeros, so zeros created by the update must not widen the cleared area. - Return the matrix with rows in their original order, values separated by single spaces and rows separated by newlines, with no extra text. - A matrix with no zeros is returned unchanged. - run case(case: dict) forwards case["stdin"] to solve .…

Normalize an absolute filesystem path

Read one absolute path and return its canonical form: empty segments and . segments disappear, .. folds into the parent, and exactly one slash separates the surviving directories.

Practice focusRequirements - The input is a single absolute path; it may repeat separators and may end with a slash. - A whole segment equal to . is dropped; only a whole segment equal to .. means "go up". - .. removes the most recently kept segment; when nothing is left to remove it has no effect, so climbing past the root stays at the root. - Join the remaining segments with one leading slash, no doubled slashes, and no trailing slash. - Return / alone when no segment survives.…

Dot product of two long integer vectors

Practice focusRequirements - Line 1 is the length n ; line 2 holds n integers for the first vector; line 3 holds n integers for the second. - Some inputs carry the two characters backslash and n instead of real line breaks; treat both forms as line separators before parsing. - Multiply matching positions, then add the products. Entries may be negative, so the sum can be negative or zero. - Return the total as a plain decimal string with no padding, no plus sign, and no newline. - Do not print the individual products or the operand vectors.…

Detect any contiguous run with a target sum

Given an integer array and a target, decide whether some non-empty contiguous run adds up to exactly that target.

Practice focusRequirements - The first line holds the element count and the target, separated by a space; the second line holds the values. - Return True when at least one such run exists and False otherwise, with exactly that capitalization and no other text. - Values may be negative or zero, so a partial sum that drifts away from the target is not evidence that no run exists. - A single element equal to the target counts, and a run may include zero-valued elements. - Stop as soon as a match is found; later runs do not change the answer.…

Water held between bars

Bars of width one stand along a line at the given heights. Return how many units of water stay trapped between them after it rains.

Practice focusRequirements - Line 1 is the bar count; line 2 lists the height of each bar from left to right. - The water above a bar is bounded by the shorter of the tallest bars on its left and on its right, minus the bar's own height. - Bars at the two ends hold nothing, and a stretch that only falls or only rises holds nothing. - Return the total as a decimal string with no per-bar breakdown and no trailing newline. - Heights are non-negative integers; the total fits in ordinary integer arithmetic. - An input with zero or one bar traps nothing.

Resolve a cd target against a working directory

You are given an absolute working directory and the argument of a cd command. Return the absolute directory the shell would land in once ., .., and repeated separators are collapsed.

Practice focusRequirements - Line 1 is an absolute working directory; line 2 is the argument, which may be absolute or relative. - An absolute argument discards the working directory and is resolved from the root. - . keeps the current directory, .. moves to the parent, and climbing past the root stays at / . - Only a whole segment equal to . or .. is special; a name such as file..name remains one segment. - Return the path with one leading slash, no repeated or trailing separators, and / alone when nothing remains.…

Palindrome after at most k deletions

Given a lowercase string and a deletion limit, decide whether removing at most that many characters can leave a palindrome while the surviving characters keep their order.

Practice focusRequirements - Line 1 is the string; line 2 is the integer limit. - Removing nothing is allowed, so a string that already reads the same in both directions always qualifies. - Each deletion is a single character, and characters that are kept never change position relative to each other. - On a mismatched pair, only two moves are worth trying: drop the left character or drop the right one. - Return true or false in lowercase, with no other text and no extra whitespace.…

Words ordered by a custom alphabet

An ordering is supplied as a permutation of the letters. Decide whether the given word list is sorted according to that ordering.

Practice focusRequirements - Line 1 is the word count; that many words follow one per line; the final line is the ordering, a permutation of the twenty-six lowercase letters. - The final line is always the ordering, so the count line only says how many words precede it. - Compare adjacent words left to right and stop at the first position where the letters differ; the letter ranked earlier wins. - If one word is a proper prefix of the other, the shorter word must appear first. - Return true or false in lowercase, with no other text.…
