Write Program for Count Pairs with Given Sum | Find Pairs of Integers in Array Summing to K (Hindi)
Description:
In this video, we explore a common problem in algorithm and coding interviews: counting the number of pairs in an array that sum up to a given value K. We will go through the problem statement, understand the input and output formats, and discuss an efficient approach to solve this problem.
We start by examining an array of integers and a target sum K. Our goal is to find and count all pairs of integers within the array whose sum equals K. Through clear examples and step-by-step explanation, we'll show you how to identify these pairs and count them effectively.
Examples Covered:
Input: arr[] = {1, 5, 7, -1}, K = 6
Output: (1, 5), (7, -1)
Explanation: Pairs with sum 6 are (1, 5) and (7, -1).
Input: arr[] = {1, 5, 7, -1, 5}, K = 6
Output: (1, 5), (7, -1), (1, 5)
Explanation: Pairs with sum 6 are (1, 5), (7, -1), and (1, 5).
Whether you're preparing for coding interviews or enhancing your algorithm skills, this video will provide you with a solid understanding of how to approach and solve this problem efficiently.
