That parameter section must declare a single parameter, the receiver. Its type must be of the form T or *T (possibly using parentheses) where T is a type name. The type denoted by T is called the receiver base type; it must not be a pointer or interface type and it must be ...
golang的map都是hash map,查找的时间复杂度是O(1),也就是说一个集合,如果用切片的方式表达,那么查找一个元素需要遍历。如果能用字典表示,则可以直接索引。 AI检测代码解析 var m map[int]string //declare a map m = make(map[int]string, 0) // init map 1....
