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: $N$ $X$ $A_1$ $A_2$ $A_3$ $\dots$ $A_N$ [samples]

Samples

Input #1

5 5
3 5 6 5 4

Output #1

3 6 4

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

Input #2

3 3
3 3 3

Output #2

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