Triplet class représente un Tuple avec trois éléments. A tuple is an immutable wrapper object that holds different pieces of information. I am currently attempting this question : A Pythagorean triplet is a set of three natural numbers, a, b and c, for which a2 + b2 = c2. For example, 32 + 42 = 9 + 16 = 25 = 52. However, as the type of the inner raw lists isn’t guaranteed, we must check if the elements in each raw list conform to Long, OP, and Long. For small arrays, a brute force approach is fine, but for larger arrays, the sorting + two pointer or hashing method is much more efficient. A simple solution is to generate all possible triplets using three nested loops and for every triplet, check if it is a Pythagorean Triplet and the sum of its elements is equal to given target.

Given a set of triplets S, where for every triplet s \\in S it holds that s[1] >= s[2] >= s[3], where s[i] is the ith element of triplet s. At its core, a fixed length tuple allows you to "loosely couple" multiple values of different types based on some sort of "ordering". However, there is no restriction on the type of the stored objects that may be stored. There e Finding a Pythagorean Triplet in an Array in Java helps improve understanding of both mathematical logic and array manipulation. If there is such a triplet present in array, then print the triplet and return true.
