Number of Divisible Triplet Sums with multiple approaches. A triplet {a, b, c} is considered a Pythagorean triplet if it satisfies the Basically, in this problem, you are given an array of integers and a target value, the triplet sum problem requires finding three elements from the Given an array arr [], and an integer target, find all possible unique triplets in the array whose sum is equal to the given target value. Find the . The solution should not include duplicate triplets. Now for each element, you check if there exists a pair whose sum is equal to targetSum - current value When you find out value, you add in final list, else you increase start or decrease end A triplet of numbers is a set of three numbers whose sum is divisible by a constant M. . In the modified array, find 3 elements whose sum is 0. Left starts at i+1 and right is at the end of the array.
