sumDouble

Programming problem at

http://codingbat.com/prob/p154485

Given two int values, return their sum. Unless the two values are the same, then return double their sum.
sumDouble(1, 2) → 3
sumDouble(3, 2) → 5
sumDouble(2, 2) → 8

My Solution

public int sumDouble(int a, int b) {

if(a==b)
return 2*(a+b);
else
return(a+b);
}

The official solution was

public int sumDouble(int a, int b) {
  // Store the sum in a local variable
  int sum = a + b;
  
  // Double it if a and b are the same
  if (a == b) {
    sum = sum * 2;
  }
  
  return sum;
}
