紫書第二個思路十分巧妙,能用很少的程式碼解出此題。

AC程式碼:

#include <iostream>
#include <algorithm>
#include <cmath>
#include <cstdlib>
#include <cstring>
#include <map>
#include <stack>
#include <queue>

#include <bitset>
#include <set>
#include <utility>
#include <sstream>
#include <iomanip>

#define ms(arr) memset(arr,0,sizeof(arr))
