    见博客

    思路
    模拟 进行字符串操作
    将操作过程写成函数 进行输出 一定要注意细节 考虑特殊情况
    如’-‘开头，’—’连在一起,还有当p1=2时数字不能和小写字母一样处理
    代码如下
    c++
    #include<iostream>
    #include<cstdio>
    #include<cstdlib>
    #include<algorithm>
    #include<cmath>
    #include<cstring>
    #define N 1000005
    using namespace std;
    char a[N];
    int p1,p2,p3;
    void deal(char x,char y){
    if(x==y-1)
    return;//如果没有展开 就直接return 因为已经输出过x和y
    char temp[500];
    int p=0;
    for(int i=x+1;i<=y-1;i++){
    for(int j=1;j<=p2;j++){
    if(p1==1) temp[++p]=i;
    else if(p1==2&&i>='a'&&i<='z')//p1=2的字母情况
    temp[++p]=i-'a'+'A';
    else if(p1==2&&i>='1'&&i<='9')//p1=2的数字情况
    temp[++p]=i;
    else if(p1==3)
    temp[++p]='*';
    }
    }
    if(p3==1)//逆序输出情况
    for(int i=1;i<=p;i++)
    cout<<temp[i];
    else if(p3==2)
    for(int i=p;i>=1;i--)
    cout<<temp[i];
    }
    int main(){
    scanf("%d%d%d",&p1,&p2,&p3);
    scanf("%s",a+1);
    int len=strlen(a+1);
    for(int i=1;i<=len;i++){
    if(a[i]=='-'){
    char x=a[i-1];
    char y=a[i+1];
    if(x>='a'&&x<='z'&&y<='z'&&y>='a'&&x<y||x>='0'&&x<='9'&&y>='0'&&y<='9'&&x<y){//满足条件 不输出'-' 输出两个字符的展开
    deal(x,y);
    //cout<<" "<<"deal"<<" ";
    }
    else cout<<a[i];//不满足 如s-4就输出'-'
    }
    else
    cout<<a[i];
    }
    }

    一道细心点就能做对的模拟题。

    下面分析下坑点和分层思路：

    坑点：

    1、"-"可能出现在第一个或最后一个，同时可能连续出现，用判断特殊处理

    2、如果x-y中x为数字而y为字母，应选择不展开！（与题目中提及的特殊情况不重叠）

    分层：

    1、是符号还是"-",同时加上对"-"的特殊处理

    2、x与y的关系，分<=、>、x+1=y

    3、x与y同时字母还是数字

    4、以p1、p3、p2的层次循环即可

    附上代码
    cpp
    #include <bits/stdc++.h>
    using namespace std;
    int p1,p2,p3;
    vector<char> ans;
    string s;
    int main()
    {
    cin >> p1 >> p2 >> p3 >> s;
    for(int i=0;i<s.size();i++)
    {
    if(s[i]!='-') ans.push_back(s[i]);
    else if((i==0 || i==s.size()-1) && s[i]=='-' ) ans.push_back('-');
    else if(s[i]=='-' && (s[i-1]=='-' || s[i+1]=='-')) ans.push_back('-');
    else if(s[i]=='-')
    {
    if(s[i-1]>=s[i+1] || (s[i-1]<58 && s[i+1]>96)) ans.push_back('-');
    else if(s[i+1]==s[i-1]+1) continue;
    else
    {
    if(p1==3)
    {
    for(int k=1;k<=(s[i+1]-s[i-1]-1)*p2;k++) ans.push_back('*');
    }
    else if(s[i+1]<=57 && s[i+1]>=48 && s[i-1]<=57 && s[i-1]>=48)
    {
    if(p3==1)
    {
    for(int k=s[i-1]+1;k<=s[i+1]-1;k++)
    for(int j=1;j<=p2;j++)
    ans.push_back(char(k));
    }

    for(int j=1;j<=p2;j++)
    ans.push_back(char(k));
    }
    }
    else if(s[i+1]<=122 && s[i+1]>=97 && s[i-1]<=122 && s[i-1]>=97)
    {

    }
    }

    for(int k=s[i-1]+1;k<=s[i+1]-1;k++)
    for(int j=1;j<=p2;j++)
    ans.push_back(char(k-32));
    }
    else if(p3==2)
    {

    }
    }
