nyoj 4 ASCII码排序 java

java输入字符：1、String s=sc.next();

2、char a=s.charAt(0);

注意：package java 中提交不能带package

java代码：

 1  
 2 import java.util.Scanner;
 3 
 4 public class Main {
 5      
 6 
 7 
 8       public static void main(String[] args)
 9       {
10           Scanner input = new Scanner(System.in);
11        int n = input.nextInt();
12        while(n-->0)
13        {
14            String string = input.next();
15            char a = string.charAt(0);
16            char b = string.charAt(1);
17            char c = string.charAt(2);
18 
19            if(a>b){char s=a;a=b;b=s;}
20            if(a>c){char s=a;a=c;c=s;}
21            if(b>c){char s=b;b=c;c=s;}
22            
23            System.out.println(a+" "+b+" "+c);
24        }
25                 
26         }    
27 }

C++：

第一次用C++写，小激动啊

 #include <iostream.h>
int main()
{
    char a,b,c,d;
    int i;
    cin>>i;
    while(i--)
    {
        cin>>a>>b>>c;
        if (a>b) {d=a;a=b;b=d;}
        if (a>c) {d=a;a=c;c=d;}
        if (b>c) {d=b;b=c;c=d;}
        cout<<a<<" "<<b<<" "<<c<<'
';
    }
    return 0;
}
