If you are given an int pair, I need my code so that it can return an int that is closest to 21 without going

Question

// blackjack(7,17) -> 17 // blackjack(21, 16) -> 21 // blackjack(19,23) -> 19 public int blackjack(int a, int b) { } 

After that, I really don't know how to write this code.

Answer 1

Hi, use this code.

 if(a<=21 && b<=21){ return Math.max(a, b); } 

This is not an easy task, try yourself next time.

Answer 2

Maybe something like this?

 private int blackjack(int a, int b) { int aa = 21-a >= 0 ? 21-a : 22; int bb = 21-b >= 0 ? 21-b : 22; if ( aa > 21 && bb > 21 ) { return -1; } return aa < bb ? a : b; }
