Before going to “The Knapsack Problem” first look at a real-life problem. Sakshi wants to carry away the maximum vegetables from a garden. However, her sack has a maximum weight capacity and might break on the addition of extra weight. Let’s look into the situation- Items: {Potato, …
Let’s understand Find Peak Element problem. Today we have with us an array that needs its peak element. Now, you must be wondering as to what do I mean by the peak element? The peak element is one which is greater than all its neighbours. Example: Given an array of …
Strongly Connected Components are the connected components of a given graph. SCC(strongly connected component) are those connected components in which every pair of a node have a path to visit from one to another node. SCC applied to Directed Graphs only. This means the path between two nodes is a …
N queen problem using the concept of Backtracking. Here we place queen such that no queen under attack condition. The attack condition of the queens is if two queens are on the same column, row, and diagonal then they are under attack. Let’s see this by the below figure. Here …
In merge sorted array problem we have given two sorted arrays in increasing order. In input first, we have given the number initialized to array1 and array2. These two-number are N and M. The size of array1 is equal to the sum of N and M. In array 1 first …
Heap sort is a comparison based sorting technique that is based on a Binary Heap data structure. HeapSort is similar to a selection sort where we find the maximum element and then place that element at the end. We repeat this same process for the remaining elements. Given an unsorted …
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 We have given an array containing N number of elements. In the given array, Count the number of triplets with a sum less than the given value. Example Input a[] = {1, 2, 3, 4, 5, 6, 7, 8} Sum = 10 Output 7 Possible triplets are : …
Problem Statement Given an array of integers, find the combination of three elements in the array whose sum is equal to a given value X. Here we will print the first combination that we get. If there is no such combination then print -1. Example Input N=5, X=15 arr[] = …
Problem Statement In a product array puzzle problem we need to construct an array where the ith element will be the product of all the elements in the given array except element at the ith position. Example Input 5 10 3 5 6 2 Output 180 600 360 300 900 …
