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 array of integers, write a program to replace its elements with the maximum element on the right side from their respective positions. Note: If the element is equal to the maximum...
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 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: The activity selection problem is a combinatorial optimization problem concerning the selection of non-conflicting activities to perform within a given time frame, given a set of activities each marked by a start time...
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 binary tree, write an algorithm to determine whether the tree is complete or not using Level order traversal. Earlier we had solved this problem by counting the number of nodes in...
Objective: Given a range, find all the numbers in the range which has prime set bits using Sieve of Eratosthenes Algorithm. Earlier we had seen a similar problem -Numbers with prime set bits in...
Objective: Given a binary tree, write an algorithm to determine whether the tree is complete or not. Complete Binary Tree: A binary tree T with n levels is complete if all levels except possibly...
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 string, write an algorithm to find the longest substring with at most K characters. Example: Input: aabbaacdeeeeddded, K = 3 Output: Longest substring with 3 most unique characters is: cdeeeeddded with...
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 graph represented by an adjacency list and a vertex, write a program to remove the given vertex and all edges connected to that vertex. Example: Approach: Earlier we had seen Graph...
Objective: Given the banks and range of routing numbers for each bank. You have given a routing number, write a program to determine which bank it belongs to. Input: Given a list of routing...
Objective: Given 1-D list of coordinates, (x1, x2), (x3, x4), , , ,(xn-1, xn)and interval (a, b). Write an algorithm to determine if interval (a,b) is covered in the list of coordinates. Example: Coordinates...
