Longest Consecutive Threshold Run

Source: Phước Hưng OJ

Version: Phuoc Hung OJ Extended

Problem Statement

Given n nonnegative numbers and threshold T, find the maximum length of a consecutive run of values at least T. A value below T resets the run.

Input

First n T, then exactly n nonnegative numbers.

Output

Print maximum qualifying run length.

Subtasks

  • Subtask 1 (20%): n ≤ 20, values and threshold ≤100.

  • Subtask 2 (30%): n ≤ 1000, values and threshold ≤10^6.

  • Subtask 3 (50%): n ≤ 100000, values and threshold ≤10^9.

Examples

Example 1

Input:

7 5
5 8 4 5 6 7 1

Output:

3

Explanation: The longest qualifying run is 5,6,7.

Example 2

Input:

3 9
0 1 8

Output:

0

Explanation: No item reaches the threshold.
