// This gist is for my YouTube video which I tried to explain Window Sliding Technique.
// You can watch it from here: https://youtu.be/guDU5HnLqAs

// Given a sorted array A (sorted in ascending order), having N integers,
// find if there exists any pair of elements (A[i], A[j]) such that
// their sum is equal to X.
//
// Input: A = [2,3,4,5,6,7,8,9], k= 10
// Output: true
// NOTE: We slightly changed the question and the output in the video. We're returning pair indexes as an array.
