Sum of all pairs in an array
Web20 Feb 2024 · Count pairs with given sum using Binary Search This approach is based on the following idea: If the array is sorted then for each array element arr [i], find the number of pairs by finding all the values ( sum – arr [i]) which are situated after ith index. This can be achieved using Binary Search. Illustration: Given arr [] = {1, 5, 7, -1}, sum = 6 Web10 Jan 2024 · Python Basic - 1: Exercise-26 with Solution Write a Python program to compute the summation of the absolute difference of all distinct pairs in a given array (non-decreasing order).
