Following are not allowed to use
1) Comparison Operators
2) String functions
Examples:
Input : num1 = 1233, num2 - 1233 Output : Same Input : num1 = 223, num2 = 233 Output : Not Same
Method 1: The idea is to use XOR operator. XOR of two numbers is 0 if the numbers are same, otherwise non-zero.
C++
#include <iostream> using namespace std; // Finds if a and b are same. void areSame(int a, int b) { if (a^b) cout << "Not Same"; else cout << "Same"; } int main() { areSame(10, 20); } |

class GFG { // Finds if a and b are same static void areSame(int a,int b) { if( (a ^ b) != 0 ) System.out.println("Not Same"); else System.out.println("Same"); } public static void main(String args[]) { areSame(10,20); } } // This code is contributed by Sumit Ghosh |

Output:
Not Same
Method 2: We can subtract the numbers. Same numbers yield 0. If answer is not 0, numbers are not same.
C++
// CPP code to check if 2 numbers are same #include <bits/stdc++.h> using namespace std; // Finds if a and b are same void areSame(int a, int b) { if (!(a - b)) cout << "Same"; else cout << "Not Same"; } // Driver code int main() { areSame(10, 20); return 0; } |
