Cryptohack- XOR Starter [10 pts]

The Solution is shared considering CAN I SHARE MY SOLUTIONS? Problem XOR is a bitwise operator which returns 0 if the bits are the same, and 1 otherwise. In textbooks the XOR operator is denoted by ⊕, but in most challenges and programming languages you will see the caret ^ used instead. A B Output 0 0 0 0 1 1 1 0 1 1 1 0 For longer binary numbers we XOR bit by bit: 0110 ^ 1010 = 1100. We can XOR integers by first converting the integer from decimal to binary. We can XOR strings by first converting each character to the integer representing the Unicode character. ...
