April Fools Day Contest 2013 - A . Mysterious Strings

这是CodeForces上很神奇的一道题，我一直搞不懂这题是怎么A的。

 

题目：

Input

The input contains a single integer a (1<=a<=40)

 

Output

Output a single string

 

这就没了。。。。。

 

 

 

AC代码：

#include<string>#include<iostream>using namespace std;const string a[]={"Washington","Adams","Jefferson","Madison","Monroe","Adams","Jackson","Van Buren","Harrison","Tyler","Polk","Taylor","Fillmore","Pierce","Buchanan","Lincoln","Johnson","Grant","Hayes","Garfield","Arthur","Cleveland","Harrison","Cleveland","McKinley","Roosevelt","Taft","Wilson","Harding","Coolidge","Hoover","Roosevelt","Truman","Eisenhower","Kennedy","Johnson","Nixon","Ford","Carter","Reagan","Bush","Clinton","Bush","Obama"};int main(){int x;cin>>x;cout<<a[x-1]<<endl;return 0;}

 

 哪位大神看懂了评论一下吧！！求解啊！
