LeetCode ProblemMaximize Y‑Sum by Picking a Triplet of Distinct X‑Values
You are given two integer arrays x and y, each of length n. You must choose three distinct indices i, j, and k such that: Your goal is to maximize the value of y[i] + y[j] + y[k] under these conditions. Return the maximum possible sum that can be obtained by choosing such a triplet of indices. If no such triplet exists, return -1.
