HDU 1062 字符串处理

题目:http://acm.hdu.edu.cn/showproblem.php?pid=1062
题目很简单,不多说
下面是自己的代码:

#include<bits/stdc++.h>
#define INF 1e18
#define inf 1e9
#define lson l,m,rt<<1
#define rson m+1,r,rt<<1|1
#define IOS ios_base::sync_with_stdio(false),cin.tie(0),cout.tie(0)
using namespace std ;
typedef long long ll;
typedef unsigned long long ull;
const int _max =1050;
int main(){
    int t;
    char c,str[_max];
    cin>>t;
    getchar();
    while(t--){
        gets(str);
        string s = str;
        string ch ,ans="";
        int len = s.length();
        int begin = 0;
        for(int i = 0 ; i < len ; i++){
            if(s[i] == ' '){
                ch = s.substr(begin,i-begin);
                begin = i+1;
                reverse(ch.begin(),ch.end());
                ans += ch;
                ans += " ";
            }
        }
        ch = s.substr(begin,len-begin);
        reverse(ch.begin(),ch.end());
        ans += ch;
        cout<<ans<<endl;
    }
    return 0;
}
