两个数是相等的，如果他们之间没有什么区别：

  INT等于（INT X，int y）对{
   返回（X-Y）！;
}
 

Using only bitwise operators (|, &, ~, ^, >>, <<) and other basic operators like +, -, and !, is it possible to replace the "==" below?

int equal(int x, int y) {
    return x == y;
}

Two numbers are equal if there is no difference between them:

int equal(int x, int y){
   return !(x-y);
}
