Why You Should NEVER Swap Numbers with Plus-Minus! ❌💀

When asked to swap two variables without a third one, most developers use the addition and subtraction method (a = a + b). It looks clever, but it has a massive flaw: Integer Overflow.
​If the variables hold very large numbers (close to INT_MAX), adding them together will exceed the memory limit of an integer. This causes an overflow, resulting in completely wrong values or program crashes! 💀
​The Safe Solution? Always use the Bitwise XOR (^) operator. It works directly on binary bits, making it 100% immune to overflows and lightning-fast!
