Given a sequence of ~n~ sorted integers ~a_0, a_1, .. , a_{n-1}~ and a positive integer ~k~, find the position ~i~ such that ~a_i~ is the largest number that is less than or equal to k. If no such number exists, return -1. If there are multiple valid positions i, choose the largest one.

INPUT

• Line 1: Two integers, ~n~ and ~k~.
• Line 2: n integers, ~a_0, a_1, .. , a_{n-1}~

OUTPUT

• The position i found

CONSTRAINTS

• ~1 \leq n \leq 10^4~
• ~-10^4 \leq k, a_i \leq 10^4~

INPUT

4 5
1 3 5 6

OUTPUT

2
