Perform exclusive-or (XOR) calculations on the four sets of values and show your work at each step. You should convert the pre-calculation values into binary and show the binary result before performing the XOR calculation. All resulting answers should also be in binary.

1) 10001 & 10100 (both are binary)

2) 42 & 26 (both are decimal)

3) AC & 4 (hexadecimal and decimal)

4) bob & run (both in ASCII)
