我知道我写的逻辑有点混乱，整体过于臃肿，但是我是打算ac了之后慢慢优化的......

VS运行截图如下：

代码如下：

#include<stdio.h>
int main()
{
    int p1, p2, p3;
    scanf("%d%d%d", &p1, &p2, &p3);
    char a[100] = { '0' };
    scanf("%s", a);

    for (int i = 0; a[i]; i++)
    {
        int flag = 0;
        if (a[i] == '-')
        {
            if ((int)a[i + 1] > (int)a[i - 1])
            {
                if (((int)a[i + 1] - 48) * (57 - (int)a[i + 1])>=0 && ((int)a[i - 1] - 48) * (57 - (int)a[i - 1]) >= 0) { flag = 1; }
                if (((int)a[i + 1] - 97) * (122 - (int)a[i + 1]) >= 0 && ((int)a[i - 1] - 97) * (122 - (int)a[i - 1]) >= 0) { flag = 2; }
                if (!flag)
                {
                    printf("-");
                    continue;
                }
                if (p1 == 3)
                {

                            printf("*");
