Pythagorean Triplet


Given an array of integers, can you write a function that returns "True" if there is a triplet (a, b, c) within the array that satisfies a^2 + b^2 = c^2?

For example:

Input: arr[] = [3, 1, 4, 6, 5]
Output: True
#There is a Pythagorean triplet (3, 4, 5) that exists in the input array.

Input: arr[] = {10, 4, 6, 12, 5}
Output: False
#There is no Pythagorean triplet that exists in the input array.
