101911: [AtCoder]ABC191 B - Remove It

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.
