jd gini nih gw rada binggung bikin flowchart dr code kyk gini

 while (numbers.size() > 0) {

 int number = getNextPossibleNumber(game, x, y, numbers);

 [I] [B] if (number == -1)

 return null;[/B] [/I]



 game[y][x] = number;

 int[][] tmpGame = generateSolution(game, index + 1);

 [I] [B] if (tmpGame != null)

 return tmpGame;[/B] [/I]

 game[y][x] = 0;

 }

terutama yg gw bold
itu kan nilai return
klo gw bikin kyk gini bener kagak ya?
