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.

Sample Input 1

5 5
3 5 6 5 4

Sample Output 1

3 6 4

Removing $5$s from \[3, 5, 6, 5, 4\] results in \[3, 6, 4\].

Sample Input 2

3 3
3 3 3

Sample Output 2

$A'$ can be a sequence with zero elements, in which case we should just print an empty line.
