Write an alternate version of squeeze(s1, s2) that deletes each character in s1 that matches any character in the string s2.

/*squeeze: delete each char in s1 which is i n s2 */
void squeeze(char s1[], char s2[]){
     int i, j, l;

   for(i=k= 0; s1[i] != '\0'; i++){
     for(j=0; s2[j] != '\0' && s2[j]  != s1[i]; j++)
        ;
     if (s2[j] == '\0')   /*end of string- no match */
        s1[k++] =s1[i];
   }
}
