Problem Statement

Given are an integer sequence $A$ of length $N$, and an integer $X$. Remove all elements that are equal to $X$ from $A$, and arrange the remaining elements without changing the order to obtain the sequence $A'$. Print $A'$.

Constraints

• $1 \le N \le 10^5$
• $1 \le X \le 10^9$
• $1 \le A_i \le 10^9$
• All values in input are integers.

Input

Input is given from Standard Input in the following format:

N X
A_1 A_2 A_3 \dots A_N

Output

Print the elements of $A'$ in order, with space in between.
