Objective: Given a string, write an algorithm to find the first non repeating character in it. Example: String input = ” tutorial horizon” Output: ‘u’ String input = “aabbccadd” Output: No non-repeating character found....
Objective: Given a string, write an algorithm to find the first repeating character in it. Example: String input = “horizon tutorials” Output: ‘o’ String input = “algorithms” Output: No repeating character found. Approach: Naive...
Objective: Given two dimensional matrix, write an algorithm to find out the snake sequence which has the maximum length. There could be many snake sequence in the matrix, you need to return the one...
Objective: Given two dimensional matrix, write an algorithm to count all possible paths from top left corner to bottom-right corner. You are allowed to move only in two directions, move right OR move down....

Objective: Given a array, write an algorithm to reverse the array. Example: int a[] = {1, 2, 3, 4, 5} Output: {5, 4, 3, 2, 1} Approach: It’s obvious that you cannot use any...
Objective: Given two dimensional matrix, write an algorithm to print all the diagonals of matrix. Example: Approach: We will solve this problem in two parts. first half of diagonals and second half of diagonals....
Objective: Given two strings, s1 and s2 and edit operations (given below). Write an algorithm to find minimum number operations required to convert string s1 into s2. Allowed Operations: Insertion – Insert a new...
Objective: In this game, which we will call the coins-in-a-line game, an even number, n, of coins, of various denominations from various countries, are placed in a line. Two players, who we will call...
Objective: Suppose you’re managing construction of billboards on the Rocky & Bullwinkle Memorial Highway, a heavily traveled stretch of road that runs west-east for M miles. The possible sites for billboards are given by...
Objective: The maximum subarray problem is the task of finding the contiguous subarray within a one-dimensional array of numbers which has the largest sum. Example: int [] A = {−2, 1, −3, 4, −1, 2, 1, −5,...

Objective: You have k lists of sorted integers. Find the smallest range that includes at least one number from each of the k lists. This is very nice and tricky solution, This problem was asked...
Objective: Given ‘N’ windows where each window contains certain number of tickets at each window. Price of a ticket is equal to number of tickets remaining at that window. Write an algorithm to sell...
Objective: Given two string sequences write an algorithm to find, find the length of longest substring present in both of them. This problem has been asked in Amazon and Microsoft interviews. Approach to solve...
