我试图找到21张5卡纸牌手,如果有5张卡纸牌和2张孔牌,它们可以组成。这是我到目前为止的内容:
public String[] joinArrays(String[] first, String[] second) {
String[] result = new String[first.length + second.length];
for (int i = 0; i < first.length; i++) {
result[i] = first[i];
}
for (int i = 0; i < second.length; i++) {
result[i + first.length] = second[i];
}
return result;
}
public String[][] getAllPossibleHands(String[] board, String[] hand){
String[] allCards = joinArrays(board, hand);
String[][] allHands = new String[21][5];
...
}
关于从这里去哪里的任何提示?我有一个由7个元素组成的数组,并希望从这些元素创建可成形的7C5(21)5个元素数组。
谢谢!
最佳答案
对于每只手,请选择7张不使用的卡中的两张。加所有其他
int cardsSelected = 0;
int hand = 0;
// select first card not to be in the hand
for(int firstCard = 0; firstCard < 7; firstCard++){
// select first card not to be in the hand
for(int secondCard = firstCard + 1; secondCard < 7; secondCard++){
// every card that is not the first or second will added to the hand
for(int i = 0; i < 7; i++){
if(i != firstCard && i != secondCard){
allHands[hand][cardsSelected++] = allCards[i];
}
}
// next hand
cardsSelected = 0;
hand++;
}
}
