9708: ABC191 —— B - Remove It
[Creator : ]
Description
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 $A'$.
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 $A'$.
Input
Input is given from Standard Input in the following format:
```
$N$ $X$
$A_1$ $A_2$ $A_3$ $\dots$ $A_N$
```
```
$N$ $X$
$A_1$ $A_2$ $A_3$ $\dots$ $A_N$
```
Output
Print the elements of $A'$ in order, with space in between.
Constraints

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

Sample 1 Input
5 5
3 5 6 5 4
Sample 1 Output
3 6 4
Removing 5s from [3,5,6,5,4] results in [3,6,4].
Sample 2 Input
3 3
3 3 3
A′ can be a sequence with zero elements, in which case we should just print an empty line.
