Problem Statement Problem “Count pairs from two linked lists whose sum is equal to a given value” state that you are given two linked lists and an integer value sum. The problem statement asked to find out how many total pair has a sum equal to the given value. Example …
Problem Statement Given an integer array, A[] with repeated elements, the “Find sum of non-repeating elements (distinct) elements in an array” problem asks to find the sum of all distinct elements in the array. So, simply add the numbers which are not repeated in the array. Example A[]={1, 4, 2, …
Problem Statement We are given a matrix of all the integers. The problem “Find distinct elements common to all rows of a matrix” asks to find out all the possible distinct elements but common in each of the rows present in a matrix. Example arr[]={ {11, 12, 3, 10}, {11, …
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 Find all permuted rows of a given row in a matrix states that you are given a matrix of size m*n and a matrix row number says ‘row’. The problem statement asks to find out all the possible rows which are permutation to the given row. This 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 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 You are given two lists. Each of which index contains the name of the item and its price. The problem statement asks to count items common to both the lists but with different prices, which is to find out how many numbers of items are common in both …
Problem Statement Suppose you have an array of integers of size n. The problem statement asks to find out the minimum number of subsets with distinct elements, that is subsets that can be formed which contain all the different/distinct elements from the array. Example arr[] = {2,4,6,2,1,4,2} 3 Explanation: {1, …
