XOR is a mathematical operator, English is exclusive OR, abbreviated as xor, applied to logical operations. The mathematical symbol of XOR is "⊕" and the computer symbol is "xor". Its algorithm is: A⊕b = (¬a ∧ b) ∨ (a ∧¬b) If the two values ​​a and b are not the same, the XOR result is 1. If the two values ​​a and b are the same, the XOR result is 0. XOR is also called semi-addition operation, and its algorithm is equivalent to binary addition without carry: binary means 1 for true, 0 means false, then XOR is: 0⊕0=0,1⊕0= 1,0⊕1=1,1⊕1=0 (same as 0, and the difference is 1). These rules are the same as the addition, except that there is no carry. XOR, abbreviated as XOR, EOR, EX-OR There are three kinds of operators in the program: XOR, xor, ⊕.
