2021年3月6日 · 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 …

2011年6月19日 · 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 …

2010年4月15日 · 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 …

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 …

My question is operator related. Today I studied about the operators. Having a confusion. In PHP what is the difference between or and xor? I know both of them are related to Boolean …

2011年1月17日 · How do you do the XOR bitwise operation if you only have available the AND and the OR operations?

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 …

2017年4月30日 · The xor operator on two booleans is logical xor (unlike on ints, where it's bitwise). Which makes sense, since bool is just a subclass of int, but is implemented to only …

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 …

如何理解「异或（XOR）」运算在计算机科学中的重要性？ 在学逻辑学的时候，基本的逻辑运算是非、与、或，且并没有得到特别的强调，而且事实上异或可以由这三个逻辑运算符表出。
