CP003075 字符串题解

这道题的解题思路如下：

1. 判断长度；
2. 若长度相等，则比较每个字符。

代码如下：

#include<bits/stdc++.h>
#define io freopen("in.txt", "r", stdin), freopen("out.txt", "w", stdout)
#define ll long long
#define ull unsigned long long
using namespace std;
// variables setting
string s1,s2;
// functions(others) defining
void sizecmp(string a,string b)
{
    int sizeA=a.size();
    int sizeB=b.size();
    if(sizeA<sizeB){cout<<a<<endl<<b<<endl;exit(0);}
    if(sizeB<sizeA){cout<<b<<endl<<a<<endl;exit(0);}
}
void cmpAChar(char a,char b)
{
    if(a<b){cout<<s1<<endl<<s2<<endl;exit(0);}
    if(a>b){cout<<s2<<endl<<s1<<endl;exit(0);}
}
void cmp()
{
    for(int i=0;i<s1.size();i++)
    {
        cmpAChar(s1[i],s2[i]);
    }
}
// the program subject
void program()
{
    cin>>s1>>s2;
    sizecmp(s1,s2);
    cmp();
}
// the main function
int main()
{
    //io;
    program();
    return 0;
}
