WebSame can be done bit-per-bit with whole numbers, and it's called bitwise operations. You must know bitwise AND, OR and XOR, typed respectively as & ^, each with just a single character. XOR of two bits is $$$1$$$ when exactly one of those two bits is $$$1$$$ (so, XOR corresponds to != operator on bits). There's also NOT but you won't use it ...

WebFirst, the XOR operation is to XOR each bit (the same is 0, the difference is 1), but you need to convert the number into a complement first. The complement of the negative number is reversed for each bit and then incremented by 1 (the highest is kept at 1) Here, the MSB bit of result will denote the sign, and the rest of the bits will denote ...
