Problem Statement “Find pairs with given sum such that elements of pair are in different rows” problem states that you are given a matrix of integers and a value called “sum”. The problem statement asks to find out all the pairs in a matrix that sums up to a given …
Problem Statement “Common elements in all rows of a given matrix” problem state that, you are given a matrix of M*N. The problem statement asks to find out all the common elements in a given matrix in each row of the matrix in O(M*N) time. Example arr[]={{12, 1, 4, 5, …
Problem Statement How to print maximum number of A’s using given four keys, this problem states that you have the option to choose which key to press. The keys perform the following tasks: Key1 – Prints ‘A’ on screen Key2 – Select the whole screen. Key3 – Copy the selected …
Problem Statement We are given a matrix of size “n x m”, and we need to collect maximum points in a grid using two traversals. If we are standing at cell i,j then we have three options to go to cell i+1, j or i+1, j-1or i+1, j+1. That is …
Problem Statement Given two unsorted arrays, find all pairs whose sum is x problem states that you are given two arrays of integers that are unsorted and a value called sum. The problem statement asks to find out the total number of pairs and print all those pairs that add …
Problem Statement Given a complete Binary Search Tree, write an algorithm to convert it into a Min Heap, which is to convert BST to Min Heap. The Min Heap should be such that the values on the left of a node must be less than the values on the right …
Problem Statement You are given an array of integers, some numbers are repeated in it. The problem statement asks to print the number in the array in decreasing order according to their frequency that is to sort elements by frequency. Example arr[]={3,4,3,1,2,9,2,9,2,5 } 2 2 2 3 3 9 9 …
Problem Statement Find the first repeating element in an array of integers problem states that you are given an array of integer. It asks to find out the first repeating element from the array and print that number. Example arr[] = {2,6,9,3,1,9,1} 9 Explanation: In the given array there are …
Problem Statement The maximum weight transformation of a given string problem states that given a string consisting only of two characters ‘A’ and ‘B’. We have an operation where we can transform string to another string by toggling any character. Thus many transformations are possible. Out of all the possible …
Problem Statement Given Two Balanced Binary Search Trees, there are n elements in the first BST and m elements in the second BST. Write an algorithm to merge two balanced binary search trees to form a third balanced Binary Search Tree with (n + m) elements. Example Input Output Pre-order …
