Ticket numbers usually consist of an even number of digits. A ticket number is considered lucky if the sum of the first half of the digits is equal to the sum of the second half. Given a ticket number n, determine if it's lucky or not.

bool isLucky(int n) {
    string s = n.ToString();
    int[] arr = new int[s.Length];
    for(int i = 0; i < s.Length; i++)
    {
        arr[i] = int.Parse(s[i].ToString());
    }
    int midpoint = arr.Length/2;
    int sum1 = 0;
    int sum2 = 0;
    
    if(arr.Length % 2 != 0)
    {
        return false;
    }
    
    
    for(int j = 0; j < midpoint; j++)
    {
        sum1 += arr[j];
    }
    for(int k = midpoint; k < arr.Length; k++)
    {
        sum2 += arr[k];
    }
    
    if(sum1 == sum2)
    {
        return true;
    }
    
    
    
    
    return false;
}
