You are working on your Boomilevers for Science Olympiad, an event that requires the breaking of various "boomilevers". For this problem, you are given a list of numbers representing the force you applied to each boomilever in pounds. You know a certain number of pounds that will always break any boomilever. Given these values, calculate how many of your boomilevers have broken so far. The first line of input contains two space-separated integers _n_ and _m_ representing the number of boomilevers, and the force required to break a boomilever, respectively. The next line contains _n_ space-separated integers representing the force applied to each boomilever. Output a single positive integer _b_: the number of boomilevers that have broken so far. ## Input The first line of input contains two space-separated integers _n_ and _m_ representing the number of boomilevers, and the force required to break a boomilever, respectively.

[samples]

**Definitions** Let $ n \in \mathbb{Z}^+ $ be the number of boomilevers. Let $ m \in \mathbb{Z}^+ $ be the minimum force required to break a boomilever. Let $ F = (f_1, f_2, \dots, f_n) $ be a sequence of integers representing the force applied to each boomilever. **Constraints** 1. $ n \geq 1 $ 2. $ m \geq 1 $ 3. $ f_i \geq 1 $ for all $ i \in \{1, \dots, n\} $ **Objective** Compute the number of boomilevers that broke: $$ b = \left| \left\{ i \in \{1, \dots, n\} \mid f_i \geq m \right\} \right| $$
