Remove character

 #include <iostream>

#include <cstring>

using namespace std;

#include "solution.h"

For a given a string(str) and a character X, write a function to remove all the occurrences of X from the given string.

The input string will remain unchanged if the given character(X) doesn't exist in the input string.

Input Format:

The first line of input contains a string without any leading and trailing spaces.

The second line of input contains a character(X) without any leading and trailing spaces.

Output Format:

The only line of output prints the updated string. 

Note:

You are not required to print anything explicitly. It has already been taken care of.

Constraints:

0 <= N <= 10^6
Where N is the length of the input string.

Time Limit: 1 second

Sample Input 1:

aabccbaa
a

Sample Output 1:

bccb

Sample Input 2:

xxyyzxx
y

Sample Output 2:

xxzxx
