Element Hunt in the Array

Given an array $BB$ of length $MM$ and a target value $YY$, your objective is to determine the presence of $YY$ within the array $BB$.

Input Specification

• The opening line should include two integers separated by a space, $MM$ and $YY$ — representing the length of the array and the target value, respectively.
• The subsequent line enumerates all elements contained within array $BB$.

Output Specification

Print "YES" if the target value $YY$ is found within $BB$; print "NO" if it is not.

Boundary Conditions

• $1\le M\le 10^{5}1\; \backslash leq\; M\; \backslash leq\; 10^5$
• $1\le B_i\le 10^{5}1\; \backslash leq\; B\_i\; \backslash leq\; 10^5$
