You are given an array of size $N$ and an integer $K$. Your task is to find the largest subarray of the provided array such that the absolute difference between any two elements in the subarray is less than or equal to $K$.

Let $M$ and $m$ be the maximum and minimum value in the selected largest subarray. Now, $M-m\le k$ must hold.

Print the length of the largest subarray.

Input format

• The first line contains two integers $N$ and $K$.
