WebMar 15, 2024 · Given an array of sorted numbers and a target sum, find a pair in the array whose sum is equal to the given target. Write a function to return the indices of the two numbers (i.e., the pair) such that they add up to the given target. One of the most popular Interview Question; Easy Level & Must Know question; There are 2 ways to solve the Pair ... WebJul 28, 2024 · l = 4, r = 3: => l > r. So break the loop. So we get count = 2. Follow the below steps to implement the idea: We will run a for loop from 0 to N-1, to find out the pivot …
Check for pair in an array with a given sum EnjoyAlgorithms
WebGiven two sorted arrays and a number x, find the pair whose sum is closest to x and the pair has an element from each array. In the case of multiple closest pairs return any one of … WebGiven an array of n integers and a target number, write a program to find whether a pair sum exists in the array or not. In other words, we need to check for a pair of elements in the array that sum exactly to the target value. Assume that all elements are distinct. Note: This is an excellent problem to learn problem solving using two pointers and hash table. diy thick shelves

A simple solution would be to consider each pair in the given array and check if the desired sum is found. The problem with this approach is that its worst-case time complexity is O(n 2), where n is the size of the input. This solution also does not take advantage of the fact that the array is circularly sorted. WebPractice this problem. There are several methods to solve this problem using brute-force, sorting, and hashing. These are discussed below: 1. Using Brute-Force. A naive solution is … diy thick stair treads
