SpletIn Python, there is a simple construct to swap variables. The following code does the same as above but without the use of any temporary variable. x = 5 y = 10 x, y = y, x print("x =", x) print("y =", y) Run Code. If the variables are both numbers, we can use arithmetic operations to do the same. It might not look intuitive at first sight. Splet3. a = a ^ b; b = b ^ a; a = a ^ b; Here is the explanation about above swap logic. Step 1, We apply bitwise XOR on variable 'a' and variable 'b' . And assign the result to variable 'a'. Step 2: We will apply the bitwise XOR on variable 'b' and variable 'a'. And then assign the result to …
