怎么用c写 求思路和代码

#include<stdio.h>
int main()
{
    int num[100][3];
    int n = 0;
    int t, s;
    scanf("%d",&n);
    for(int i = 1; i <= n; i++)
    {
        scanf("%d",&num[i][0]);
        num[i][1] = i;
        num[i][2] = i;
    }

    for(int i = 1; i <= n - 1; i++)
     for(int j = 1; j <= n - i; j++)
    {
        if(num[j][0] < num[j+1][0])
        {
            s = num[j][0];
            num[j][0] = num[j+1][0];
            num[j+1][0] = s;
            t = num[j][1];
            num[j][1] = num[j+1][1];
            num[j+1][1] = t;
            num[num[j+1][1]][2]++;
            num[num[j][1]][2]--;
        }
    }
    for(int i = 1; i <= n; i++)
    printf("%d %d \n",num[i][0],num[i][2]);
    return 0;
}

用脑子写c，谢谢😊
