Java > Logic-2 > blackjack (CodingBat Solution)

Problem:

Given 2 int values greater than 0, return whichever value is nearest to 21 without going over. Return 0 if they both go over.

blackjack(19, 21) → 21
blackjack(21, 19) → 21
blackjack(19, 22) → 19

Solution:

public int blackjack(int a, int b) {
  if (a > 21 && b > 21) {
      return 0;
  }else if (a > 21) {
      return b;
  } else if (b > 21) {
      return a;
  }
  
  int sumA = 21 - a;
  int sumB = 21 - b;
  
  if (sumA > sumB) {
      return b;
  } else {
      return a;
  }
  
}
