LeetCode ProblemMerge Triplets to Form Target Triplet
A triplet is an array of three integers. You are given a 2D integer array triplets, where triplets[i] = [ai, bi, ci] describes the ith triplet. You are also given an integer array target = [x, y, z] that describes the triplet you want to obtain. To obtain target, you may apply the following operation on triplets any number of times (possibly zero): Return true if it is possible to obtain the target triplet [x, y, z] as an element of triplets, or false otherwise.
