Objective: Given an array of integers and number N, Write an algorithm to find and print all the unique subsets of array for which sum is equal to N where array elements can be...
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 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...
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 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 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...
Objective: Given a two-dimensional array or matrix, Do the depth-First Search (DFS) to print the elements of the given matrix. Implement the Depth-first traversal in a recursive manner. Example: int [][] grid = new...
Objective: Given a 2d grid map of ‘1’s (land) and ‘0’s (water), count the number of islands. An island is surrounded by water and is formed by connecting adjacent lands horizontally or vertically. Assume...
Objective: Given a number N, write an algorithm to find the maximum number of steps it takes to transform (1, N) to 1 using Collatz Conjecture. The Collatz conjecture is a conjecture in mathematics...
Objective: Given a stack, write a program to print the stack elements in reverse order. Example: Approach: Use Temporary stack: Take temporary stack, and copy all the items from the given stack to a...
Objective: Given an array of numbers, write an algorithm to print all the subsets sum individually. Example: Given Input: [1, 2] Output: 3 1 2 0 Explanation: subsets are [0], [1], [2], [1, 2]...
Objective: Given two integers N and K. Write an algorithm to find all the combinations of k numbers which sum to N. Conditions: All K numbers must be between 1 and 9 and unique....
Objective: Given an array of integers write an algorithm to find all the subsets for which sum is equal to zero. The array contains both positive and negative integers. Example: Given Array: [8, 3,...
Objective: Given a 2d grid map of ‘1’s (land) and ‘0’s (water), count the number of islands. An island is surrounded by water and is formed by connecting adjacent lands horizontally or vertically. Assume...
