Dados dos números, la tarea es verificar si dos números son iguales sin usar operadores aritméticos y de comparación o funciones de string.
Método 1: La idea es usar el operador XOR. XOR de dos números es 0 si los números son iguales, de lo contrario no es cero.
C++
// C++ program to check if two numbers // are equal without using arithmetic // and comparison operators #include <iostream> using namespace std; // Function to check if two // numbers are equal using // XOR operator void areSame(int a, int b) { if (a ^ b) cout << "Not Same"; else cout << "Same"; } // Driver Code int main() { // Calling function areSame(10, 20); }
Java
// Java program to check if two numbers // are equal without using arithmetic // and comparison operators class GFG { // Function to check if two // numbers are equal using // XOR operator static void areSame(int a, int b) { if ((a ^ b) != 0) System.out.print("Not Same"); else System.out.print("Same"); } // Driver Code public static void main(String[] args) { // Calling function areSame(10, 20); } } // This code is contributed by Smitha
