In this article, we are given a matrix of size m x n and an integer variable X. The row elements and the first column of the matrix are sorted in increasing order. Our task is to count the number of elements that are equal ... Read More

In this article, we have an unsorted array of integers having repetitive elements. Our task is to count the distinct elements in the given array in C++. Example Here is an example of counting the unique number in the given array: Input: array = {4, 2, 32, ... Read More

In this article, we will solve a sum array puzzle, where we have an array with n elements. We have to create another array of n elements such that the 'ith' position of the second array will hold the sum of all elements of the ... Read More

A sorted and rotated array is an array that is sorted in ascending or descending order and then rotated either left or right by a specific number of elements. There should exist exactly one pivot point around which the array is rotated. Example Here ... Read More

In this article, we have a sorted array of integers. Our task is to find the count of elements of the given sorted array that are less than or equal to the given value K. Example Here are some examples of counting the array elements smaller than the given ... Read More

In this problem, we are given an array arr[] consisting of N sorted integer values and an integer k. Our task is to Find the number of elements greater than k in a sorted array. Example Here are some examples of counting the array elements greater than the given target ... Read More

JavaScript Program for the Number of local extrema in an array is a common problem in the field of computer science and data analysis. Local extrema are the peaks and valleys in a sequence of numbers. In this article we are having two arrays, our task is to write a ... Read More

To implement block swap algorithm for array rotation, we will be understanding three different approaches. Rotation of the array elements means moving the elements of the given array to either the left or right side by some number of specific positions. Block swap algorithm for array rotation means to rotate ... Read More
