Mar 6, 2021 · The XOR ( ^ ) is an logical operator that will return 1 when the bits are different and 0 elsewhere. A negative number is stored in binary as two's complement. In 2's complement, …

Jun 19, 2011 · The compiler will just produce assembly code to XOR a register onto itself). Now, if X XOR X is 0, and XOR is associative, and you need to find out what number hasn't repeated …

XOR evaluation, as you understand, cannot be short-circuited since the result always depends on both operands. So 1 is out of question. But what about 2? If you don't care about 2, then with …

Apr 15, 2010 · XOR behaves like Austin explained, as an exclusive OR, either A or B but not both and neither yields false. There are 16 possible logical operators for two inputs since the truth …

2 one is exclusive or -> xor, and the other is or which means at least one of the conditions are met in a truth table. Or is not mutually exclusive, xor is.

But a "logical" xor operator (^^) would always have to evaluate both operands. This makes it different to the other "logical" operators which evaluate the second operand only if necessary. I …

Jan 17, 2011 · How do you do the XOR bitwise operation if you only have available the AND and the OR operations?

I am having some trouble identifying when to use the XOR operator when doing bitwise manipulations. Bitwise And and Or are pretty straight forward. When you want to mask bits, …

My question uses Java as an example, but I guess it applies to probably all. Is there any practical difference between the XOR operator (^ in Java) and the not-equal-to operator (!= in Java), when

In an XOR linked list, you store one 'pointer' per node, which is the XOR of prev and next (or if one of them is absent, just the other (the same as XORing with 0)). The reason why you can …
