HUT-XXXX The window of the dazzling 模拟

算出每个窗户左上角和右下角的坐标，直接模拟就行了。

这题直接把sum放在G数组后面，导致sum变成了char型，错了一次，G数组第一次只开了105～～～。

代码如下：

#include <cstring>

#include <cstdio>

#include <cstdlib>

using namespace std;



char G[600][600];

int sum[10];



int main()

{

    int N, M, x1, y1, x2, y2, cnt;

    while (scanf("%d %d", &N, &M) == 2) {

        memset(sum, 0, sizeof (sum));

        for (int i = 0; i < 5 * N + 1; ++i) {

            scanf("%s", G[i]);

        }

        for (int i = 0; i < N; ++i) {

            for (int j = 0; j < M; ++j) {

                cnt = 0;

                x1 = 5 * i + 1;

                y1 = 5 * j + 1;

                x2 = 5 * i + 4;

                y2 = 5 * j + 4;

                for (int p = x1; p <= x2; ++p) {

                    for (int q = y1; q <= y2; ++q) {

                        if (G[p][q] == '*') {

                            ++cnt;

                        }

                    }

                }

                ++sum[cnt/4];

            }

        }

        for (int i = 0; i < 5; ++i) {

            printf(i == 0 ? "%d" : " %d", sum[i]);

        }

        puts("");

    }

    return 0;

}
