Longest Substring Without Repeating Characters

Given a string S, write a program to find the length of longest substring without repeating characters. The substring is a continuous subpart of the string and we need to return the largest substring which has all unique characters. Note: This is an excellent problem to learn problem solving and time complexity optimization using sliding window approach.

Max Consecutive Ones

A binary array X[] is given where elements are either 0 or 1. Write a program to find the maximum consecutive ones. The subarray with max continuous 1's can be present anywhere, starting from some index i and ending at some index j. This is an excellent problem to learn problem solving using a sliding window approach and single loop.

Max Continuous Series of 1s

You are given an array of 1s and 0s and you are given an integer k which signifies the number of flips allowed. Write a program to find the position of zeros which when flipped will produce a maximum continuous series of 1s. Note: This is an excellent problem to learn problem solving using sliding window technique in O(n) time and O(1) space.

Count Distinct Elements in Every Window

Given array X[] of n integers, write a program to return the count of distinct elements in every window of size k. Here k sized window is a continuous subarray of k elements, and output is an array with the count of unique elements in each window. Note: This is an excellent problem to learn problem-solving using the sliding window approach.
