In the range minimum query problem we have given a query and an integer array. Each query contains the range as left and right indexes for each range. The given task is to determine the minimum of all number that lies within the range. Example Input: arr[] = {2, 5, …
In the range sum query using sparse table problem we have a range query and given an integer array. The given task is to find out the sum of all integers that comes in the range. Example Input: arr[] = {1,4,6,8,2,5} Query: {(0, 3), (2, 4), (1, 5)} Output: 19 16 25 …
An array of size n has been given as an input value. The problem “Count and Toggle Queries on a Binary Array” asks to perform some of the queries which are given below, queries can vary in a random manner. The queries are ⇒ Toggle query ⇒ toggle(starting, ending), this …
Write Queries for decimal values of subarrays of a binary array in a given binary array. The problem statement asks to find out the decimal number so formed with the help of range in a binary array. Example Input: arr[] = {1, 0, 1, 1, 0, 0, 1, 1} Query(1, …
Suppose, we have given two integers array of same size n. Both of the arrays contain positive numbers. The problem statement asks to maximize the first array by using the second array element keeping the second array as a priority (elements of the second array should appear first in output). …
The problem “Find whether an array is subset of another array” states that you are given two arrays arra1[] and array2[]. The arrays given are in an unsorted manner. Your task is to find whether the array2[] is a subset of array1[]. Example arr1= [1,4,5,7,8,2] arr2= [1,7,2,4] arr2 [] is …
The problem “Minimum swaps required to bring all elements less than or equal to k together” states that you have an integer array. The problem statement asks to find out the smallest count of swaps that will be required to get the elements together which are less than or equal …
The problem “Maximum sum of pairs with specific difference” states that you are given an array of integers and an integer K. Then we are asked to find out the maximum sum of independent pairs. We can pair two integers if they have an absolute difference of less than K. …
Problem statement In this article titled “Find First and Last Position of Element in Sorted Array Leetcode Solution,” we will discuss the solution to a leetcode problem. In the given problem we are given an array. We are also given a target element. Elements in the array are sequenced in …
Problem statement In the problem “Monotonic Array” we are given an array. Our task is to check if the array is a monotonic array or not. A monotonic array is an array where elements are either sorted in increasing order or in decreasing order. If the array is sorted in …
