loneSum

Goto Problem

Given 3 int values, a b c, return their sum. However, if one of the values is the same as another of the values, it does not count towards the sum.loneSum(1, 2, 3) → 6
loneSum(3, 2, 3) → 2
loneSum(3, 3, 3) → 0

public int loneSum(int a, int b, int c) {

    if(a==b)
    {
      if(a==c) 
        return 0;
      else 
        return c;
     }

    if(a==c)
    {
        return b;
    }
    if(b==c) 
       return a;
    else 
       return a+b+c;
}
