Count pairs in a sorted array whose sum is less than x

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. WebOct 22, 2024 · Since the number of such pairs can be very large, return number of such pairs modulo (10 9 + 7). Observation : 1. If the array is sorted and the sum of two elements is less than expected sum, moving left pointer would help and vice versa. 2. If there are duplicate elements – Each duplicate element will contribute to multiple pairs.
