            if (bbb.Equals(aaa))
            {
                answer = 1;
            }
            else
            {

    }
}

----------------------------

using System;
using System.Collections.Generic;

public class Solution {
    public int solution(string before, string after) {
        int answer = 0;
        
            List<char> b = new List<char> { };
            List<char> a = new List<char> { };

            foreach (char j in before)
            {
                b.Add(j);
                b.Sort();
            }

            foreach (char j in after)
            {
                a.Add(j);
                a.Sort();
            }

            string b1 = string.Join("", b);
            string a1 = string.Join("", a);

            if (b1 == a1)
            {
                answer = 1;
            }
            else
            {
                answer = 0;
            }
        
        return answer;
       
    }
}

이렇게 두가지 방식을 쓸수있다고 한다
