#include<stdlib.h>
#include<string.h>
int main()
{
    int i,len;
    char c;
    char array[1000];
    while(gets(array))
    {
        scanf("%c",&c);
        len = strlen(array);
        for(i = 0;i < len;i++)
        {
            if(array[i] == c)
            continue;
            else
            printf("%c",array[i]);
        }
        printf("\n");
        getchar();
    }
    return 0;
}

Java :

import java.util.*;

public class Main{
  final static Scanner jin=new Scanner(System.in);
  public static void main(String args[]){
    while(jin.hasNextLine()){
      char str[]=jin.nextLine().toCharArray();
      char c=jin.nextLine().toCharArray()[0];
      for(int i=0;i<str.length;i++)
    	  if(str[i]!=c)
    		  System.out.print(str[i]);
      System.out.println();
    }
  }
}
