first sort the array , then run a n^2 for loop . For every ar[i]+ar[j] , i find out the frequency of ar[i]+ar[j] from index j+1 to n in array ar[] . Then i add this frequency to the answer . To evaluate "frequency of ar[i]+ar[j] from index j+1 to n in array...
Given an array S of n integers, are there elements a, b, c in S such that a + b + c = 0? Find all unique triplets in the array which gives the sum of zero. Note: Elements in a triplet (a,b,c) must be in non-descending order. (ie, a ≤ b ≤ c) The solution set mus...
