【思路】:找规律,参考的别人的,自己写的挂了。http://blog.csdn.net/appte/article/details/8227632

【AC代码】:

#include <iostream>#include <cstdio>#include <cstdlib>#include <cstring>using namespace std;int main(){    //freopen("in.txt", "r", stdin);    //freopen("out.txt", "w", stdout);    int T = 0;    cin >> T;    while (T--)    {        int n = 0, m = 0;        cin >> n;        if (n<200)            m = n%150;        else if (n >= 200 && n < 300)            m = n%200;        else if (n >= 300)            m = n%50;        cout << m << endl;    }    return 0;}

【自己写的WA代码】:1300时候就是错的,应该是0,输出50。

#include <iostream>#include <cstdio>#include <cstdlib>#include <cstring>using namespace std;int main(){    //freopen("in.txt", "r", stdin);    //freopen("out.txt", "w", stdout);    int T = 0;    cin >> T;    while (T--)    {        int n = 0;        cin >> n;        int a = n%150, b = n%200, c = n%350;        if (b >= 150)            b %= 150;        if (c >= 300)            c %= 150;        else if (c >= 200)            c %= 200;        else if (c >= 150)            c %= 150;        if (a < b)        {            if (a < c)                cout << a << " ";            else                cout << c << " ";        }        else        {            if (b < c)                cout << b << " ";            else                cout << c << " ";        }    }    return 0;}

方法就是错的,几乎没法改。。
