XOR is a digital logic gate that gives a true output when there is an odd number of true inputs. It is also known as exclusive OR. If both the inputs are true, then the result will be false and vice versa. Let x and y be the two variables on which XOR gate operate. 1 2 3

The XOR of them is X, the task is to find the number of ways to swap two-bit positions in string s1 such that XOR formed between new s1 and s2 is not same as X. Examples: Input: s1 = “01011”, s2 = “11001” Output: 4 swap bits of index (1-based) (1, 4), (2, 3), (3, 4), or (3, 5) such that XOR value is changed.

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.
