C语言oj搞不清楚，我觉得我的根样例的挺像的

Question

#include <stdio.h>  
#include <string.h>  
  
#define MAX_NAME_LENGTH 20  
#define MAX_TEST_COUNT 1000  
  
struct Title {  
    char name[MAX_NAME_LENGTH];  
    int count;  
};  
  
int main() {  
  int t;
  scanf("%d",&t);
  while(t--)
  { 
    int test_count;  
    scanf("%d", &test_count);  
  
    struct Title title[MAX_TEST_COUNT];  
    int i, j;  
    for (i = 0; i < test_count; i++) {  
        scanf("%s %d", title[i].name, &title[i].count);  
    }  
  

    for (i = 0; i < test_count - 1; i++) {  
        for (j = i + 1; j < test_count; j++) {  
            if (title[i].count < title[j].count) {  
                struct Title temp = title[i];  
                title[i] = title[j];  
                title[j] = temp;  
            }  
        }  
    }  
  

    for (i = 0; i < test_count; i++) {  
        printf("%s\n", title[i].name);  
    }  
  
    return 0;  
}
}

为什自己运行出来我觉得没问题，在oj里面却是答案错误呢

将第43行放到while循环后面试试，因为测试组数t可能不止一组。

修改如下：

#include <stdio.h>
#include <string.h>

#define MAX_NAME_LENGTH 20
#define MAX_TEST_COUNT 1000

struct Title {
    char name[MAX_NAME_LENGTH];
    int count;
};

int main() {
    int t;
    scanf("%d",&t);
    while(t--) {
        int test_count;
        scanf("%d", &test_count);

        struct Title title[MAX_TEST_COUNT];
        int i, j;
        for (i = 0; i < test_count; i++) {
            scanf("%s %d", title[i].name, &title[i].count);
        }


        for (i = 0; i < test_count - 1; i++) {
            for (j = i + 1; j < test_count; j++) {
                if (title[i].count < title[j].count) {
                    struct Title temp = title[i];
                    title[i] = title[j];
                    title[j] = temp;
                }
            }
        }


        for (i = 0; i < test_count; i++) {
            printf("%s\n", title[i].name);
        }

    
    }
    
    return 0;  // 将这行代码放到while循环后面，因为数据组数可能不止一组 
}
