Objective: Given two strings, source string and target string, which are permutation or anagram of each other. You are allowed two swap only consecutive characters. Write an algorithm to print all the steps (...
Objective: Given an array of integers (in particular order or permutation of a set of numbers), write an algorithm to find the lexicographically next permutation of the given permutation with only one swap. This...
Objective: Given two integers N and K, Write an algorithm to find subsets of size K from the numbers 1 to N. Example: N = 5 K = 3 Output: [1, 2, 3] [1,...
Objective: Given two integers N and K, Write an algorithm to find possible combinations that add to K, from the numbers 1 to N. Condition: An integer from 1 to N can be repeated...
Stable Marriage Given N men and N women and the marriage preference order for each man and woman. Their marriage will be stable when these men and women marry in such a manner so...
Objective: Given an array of integers, write an algorithm to construct the largest number possible by appending the array elements. Example: Given Input: [7, 78] Largest Number Possible: 787 Explanation: two possibilities are 778...
Objective: Given an array of integers, find the sum of any three elements which is closest to zero. The array may contain positive and negative elements. Example: Given Input: [-1, 4, -2, 5, 10,...
Objective: Given an array of integers and number N, Write an algorithm to find and print all the subsets of the array for which sum is equal to N. Example: input [] = {6,2,7,8,2,4,1,3,7,5}...
Objective: Given an array of numbers and integer K. Your task is to find lengths of all the subsets which contain value K and all elements in the subset are less than equal to...
Objective: Given an integer N, Write an algorithm to select numbers from 1 to 9 and make combinations such that its sum to N. Example: N= 5 Output: [1, 4] [2, 3] [5] N...
Objective: Given a list of intervals with start and end for each interval. You have given a value V, write an algorithm to find the number of intervals in which the value V lies. ...
Objective: Given an integer N, write a function to return an array containing N unique integers that sum up to zero. There are many possible arrays that sum up to 0 for any N,...
Objective: Given a graph, write an algorithm to find all the articulation points or cut vertices. Articulation Points: In a graph, a vertex is called an articulation point if removal of that vertex (along...
Objective: Given an undirected graph, Write an algorithm to determine whether its tree or not. An undirected graph is a tree if it has properties mentioned below There is no cycle present in the...
Objective: Given a 2d grid map of ‘1’s (land) and ‘0’s (water), count the number of distinct or unique islands. Island: An island is surrounded by water and is formed by connecting adjacent lands...
