factorial - Why does 0! = 1? - Mathematics Stack Exchange
网页The theorem that (n k) = n! k!(n−k)! (n k) = n! k! (n − k)! already assumes 0! 0! is defined to be 1 1. Otherwise this would be restricted to 0 <k <n 0 <k <n. A reason that we do define 0! 0! to be 1 1 is so that we can cover those edge cases with the same formula, instead of having to treat them separately.
Zero to the power of zero - Wikipedia
网页Zero to the power of zero, denoted by 00, is a mathematical expression that is either defined as 1 or left undefined, depending on context. In algebra and combinatorics, one typically defines 00 = 1. In mathematical analysis, the expression is sometimes left undefined.

网页1. 与 运算（&） 参加运算的两个数据，按二进制位进行“与”运算。 运算规则：0&0=0; 0&1=0; 1&0=0; 1&1=1; 即：两位同时为“1”，结果才为“1”，否则为0. 例如：3&5 即 0000 0011 & 0000 0101 = 0000 0001 因此，3&5的值为1。 例如：9&5 即 0000 1001 (9的二进制补码)&00000101 (5的二进制补码) =00000001 (1的二进制补码)可见9&5=1。 2.或运算（|） 参加运算的两个对象，按二进制位进行“或”运算。 运算规则：0|0=0； 0|1=1； 1|0=1； …
