Problem Statement We need to find the order of multiplication of matrices such that the number of operations involved in the multiplication of all the matrices is minimized. Then we need to print this order i.e. printing brackets in matrix chain multiplication problem. Consider you have 3 matrices A, B, …
Three Sum is a problem loved by interviewers. It is a problem I was personally asked during the Amazon interview. So, without wasting any more time let us get to the problem. An array that has both positive and negative numbers. Three numbers that sum up to zero/can be modified, …
Least Recently Used (LRU) Cache is a type of method which is used to maintain the data such that the time required to use the data is the minimum possible. LRU algorithm used when the cache is full. We remove the least recently used data from the cache memory of …
Given an integer array and an integer k. Find total number of contiguous subarrays of given array whose sum of elements is equal to k. Example Input 1: arr[] = {5,0,5,10,3,2,-15,4} k = 5 Output: 7 Input 2: arr[] = {1,1,1,2,4,-2} k = 2 Output: 4 Explanation : consider example-1 …
Problem Statement In the given unsorted array, find the pair of elements in the given array with given difference n. Example Input arr[] = {120, 30, 70, 20, 5, 6}, difference(n) = 40 Output [30, 70] Explanation Here the difference of 30 and 70 is equal to the value of …
Problem Statement In the subarray with the given sum problem, we have given an array containing n positive elements. We have to find the subarray in which the sum of all the elements of the subarray equal to a given_sum. Subarray is obtained from the original array by deleting some …
Problem Statement We have given an array of containing different elements or no repeated elements present in the array. Find all pairs with a given difference. If there is no any pair with given different then print “No pair with given different”. Example Input 10 20 90 70 20 80 …
