• [tab]
• C++

• #include<iostream>
  #include<algorithm>
  using namespace std;
  int main()
  {
  	string s;
  	char a[100];
  	cin >> s;
  	int j = 0;
  	for (int i = 0;i < s.length();i++)
  	{
  		if (s[i] != '+')
  		{
  			a[j] = s[i];
  			j++;
  		}
  	}
  	sort(a, a + j);
  	for (int i = 0;i < j;i++)
  	{
  		if (i == j - 1) cout << a[i] << endl;
  		else cout << a[i] << "+";
  	}
  	return 0;
  }

• Python3

• s = input().split("+")
  s.sort()
  print("+".join(s))

• JAVA

• import java.util.Arrays;
  import java.util.Scanner;
   
  public class PracticeCF {
   
  	public static void main(String[] args) {
  		Scanner sc=new Scanner(System.in);
  		String s=sc.next();
  		s=s.replace("+", "");
  		char arr[]=s.toCharArray();
  		Arrays.sort(arr);
  		for(int i=0;i<s.length();i++)
  		{
  			if(i==0)
  			{
  				System.out.print(arr[i]);
  			}
  			else
  			{
  			System.out.print("+"+arr[i]);
  			}
  		}
  		
  	}
