打开以下链接可以查看正确的代码
https://ac.nowcoder.com/acm/contest/5657#question
输入描述:
多个测试用例,每个测试用例一行。
每行通过,隔开,有n个字符,n<100
输出描述:
对于每组用例输出一行排序后的字符串,用','隔开,无结尾空格
示例1
输入
复制
a,c,bb
f,dddd
nowcoder
输出
复制
a,bb,c
dddd,f
nowcoder
思路和心得:
输入时
1.c++可以用stringstream
//c++代码
#include <bits/stdc++.h>
using namespace std;
int main()
{
string s;
while (cin >> s)
{
stringstream ss;
ss << s;
vector<string> words;
string word;
while (getline(ss, word, ','))
{
words.push_back(word);
}
sort(words.begin(), words.end());
for (int i = 0; i < (int)words.size() - 1; i ++)
cout << words[i] << ',';
cout << words.back() << endl;
}
return 0;
}2.python3 可以用str.split(',')
#python3代码
while True:
try:
words = input().split(',')
words.sort()
for word in words[:-1]:
print(word, end = ',')
print(words[-1])
except:
break3.java可以用nextLine().split(",")
//java代码
import java.util.*;
public class Main
{
public static void main(String [] args)
{
Scanner scan = new Scanner(System.in);
while (scan.hasNextLine())
{
String[] words = scan.nextLine().split(",");
Arrays.sort(words, (w1, w2) -> w1.compareTo(w2));
int wn = words.length;
for (int i = 0; i < wn - 1; i ++)
{
System.out.print(words[i] + ',');
}
System.out.println(words[wn-1]);
}
}
}
