题解

非常好的一道模拟题。
纯模拟就行，把脑子拿出来寄存一下，然后无脑模拟就行。

#include <bits/stdc++.h>
using namespace std;
typedef long long ll;
vector<string> ves(110,"");
int main()
{
    int p1,p2,p3;
    cin>>p1>>p2>>p3;
    string s;
    cin>>s;
    for(int i=0;i<s.length();i++)
    {
        if(0<=i-1&&i+1<s.length()&&s[i]=='-'&&!(isdigit(s[i-1])^isdigit(s[i+1]))&&s[i-1]<s[i+1]&&s[i-1]!='-'&&s[i+1]!='-')
        {
            char c=s[i-1]+1;
            int cnt=0;
            for(;c<s[i+1];c++)
            {
                for(int j=1;j<=p2;j++)
                {
                    if(p1==2&&!isdigit(c)) ves[i]+=char(c-32);
                    if(p1==3) ves[i]+='*';
                    else if(p1==1||isdigit(c)) ves[i]+=c;
                }
            }
            if(p3==2)
            {
                reverse(ves[i].begin(),ves[i].end());
            }
        }
    }
    for(int i=0;i<s.length();i++)
    {
        if(0<=i-1&&i+1<s.length()&&s[i]=='-'&&!(isdigit(s[i-1])^isdigit(s[i+1]))&&s[i-1]<s[i+1]&&s[i-1]!='-'&&s[i+1]!='-') cout<<ves[i];
        else cout<<s[i];
    }
}
