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:

NN XX

A1A_1 A2A_2 A3A_3 \dots ANA_N

Output

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


5 5
3 5 6 5 4
3 6 4

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


3 3
3 3 3

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