Interview experiences & questions tagged Sliding Window
Given two strings, S and T, find the minimum window in S which will contain all the characters of T. If there is no such window, return the empty string. Example: Input: S = 'ADOBECODEBANC', T = 'ABC'. Output: 'BANC'.
Given an array of positive integers and a target value, find the minimal length of a contiguous subarray of which the sum is greater than or equal to the target value. If no such subarray exists, return 0. Example: Input: nums = [2,3,1,2,4,3], target = 7. Output: 2.
Solve DSA problems that utilize the sliding window technique and binary search. Focus on implementing algorithms using these strategies.
Describe a method for optimizing a subarray traversal with a character frequency constraint. Consider the performance implications of your approach.
Given a string `s`, find the length of the longest substring without repeating characters.
