Pair Difference Finder

Pair Difference Finder

Given a list of integers and a target integer, determine whether there exists a pair of elements in the list whose difference is exactly equal to the target value. Formally, for a given array \(A = [a_1, a_2, \ldots, a_n]\) and an integer \(d\), find if there exists a pair \((a_i, a_j)\) such that \(a_i - a_j = d\).

You are required to read input from standard input (stdin) and output your answer to standard output (stdout). The answer should be either True or False.

inputFormat

The first line contains two integers, (n) (the number of elements in the list) and (d) (the target difference). The second line contains (n) space-separated integers representing the list.

outputFormat

Output a single line with either True if there exists at least one pair ((a_i, a_j)) in the list such that (a_i - a_j = d), or False otherwise.## sample
