There is an array s [1] = 1, s [2] = 1 2 ,....... s [k] = 1 .... k. a given n is required to represent the nth digit of the array and the nth digit is required. For example, when n is 1, when 1 n is 2, it is 1, and when n is 3, it is 2. Solution: 1:

Pay attention to the following points: 1. Pie turning rules: You can only flip from the bottom layer, that is, reverse the first I element. So here is a tip, that is, find the largest element in the first I element (assuming the first m), and turn

Sometimes you need to reload the operator to write a class, but some operators (such as =, ) can be written in the class or out-of-class. So how will the C ++ compiler call it? First, we know that the "overload" mechanism allows multiple functions
