UVa 10161: Ant on a Chessboard

很简单的一题找规律题。

我的解题代码如下：

#include <iostream>#include <cstdio>#include <cstring>#include <cmath>#include <cstdlib>#include <string>#include <algorithm>using namespace std;int main(){int N;while(cin >> N && N!=0){int level = floor(sqrt(double(N-1)))+1;int middle = (level-1)*(level-1)+level;//cout << "level: " << level << " middle: " << middle << endl;if(level%2) {if(N<middle) cout << level << ' ' << level+N-middle << endl;else cout << level-N+middle << ' ' << level << endl;}else {if(N<middle) cout << level+N-middle << ' ' << level << endl;else cout << level << ' ' << level-N+middle << endl;}}return 0;}
