Since number could be 10^100, we have to use large number processing method, in string. A simpler method is to pre-calculate all Fibonacci numbers up to 101 digits, which is already fast enough. #include <vector> #include <iostream> #include &…

详解一下之前的解构赋值 ①解构赋值中的"..." let [a,...b]= [1]; b // [] ...代表变量b去匹配剩余的所有元素返回一个数组 ,匹配不到时返回[] //注意:"...b"只能放在最后 ②解构赋值的等号两边的数据类型必须一样 即: let [] = [] 或者 let {} = {} 但是:Set结构也允许使用数组进行解构赋值 let [a,b]= new Set([1,2,3,4]) a b 技巧: 如果你不确定该结构是否能够解构赋值,判…
