Find Pair with Given Difference

You are given a sorted list of integers \( arr \) of length \( N \) and an integer \( K \). Your task is to determine whether there exist two distinct elements \( arr[i] \) and \( arr[j] \) such that the difference satisfies

\( arr[j] - arr[i] = K \)

If such a pair exists, print True; otherwise, print False.

Note: The input is provided via the standard input (stdin) and the output should be printed to the standard output (stdout).

inputFormat

The first line contains two integers \( N \) and \( K \) separated by a space.

The second line contains \( N \) sorted integers separated by spaces.

Example:

5 4
1 3 5 9 11

outputFormat

Output a single line containing either True or False (without quotes) indicating whether a pair with the given difference exists.

## sample
