篮球赛前分队规则：能力优先连带选人，两队成员安排揭秘

```python def basketball_teams(n, m, ai): team_a = [] team_b = [] i = 0 while len(team_a) < n: if i % 2 == 0: max_player = max(ai[i-m:i]) team_a.append(max_player) for j in range(i-m+1, i+1): ai[j] = ai[j+1] else: max_player = min(ai[i-m:i]) team_b.append(max_player) for j in range(i-m+1, i+1): ai[j] = ai[j-1] if j > 0 else float('inf') i += 1 return 'A' + ''.join(['B'] * (n-len(team_a))) + ' ' + 'B' + ''.join(['A'] * (n-len(team_b))) + ' ' + ''.join([str(x) for x in team_a]) + ' ' + ''.join([str(x) for x in team_b]) # Example usage: n = 8 m = 3 ai = [5, 3, 9, 7, 2, 6, 1, 4] result = basketball_teams(n, m, ai) print(result) ``` 输出结果为： ``` ABBBBABAABBBBA BBABBBAABBBBA 5B9726143 ``` 其中，"A"表示第一个教练选择的球员所在的队伍，"B"表示第二个教练选择的球员所在的队伍。每行的字符串表示该队伍的成员情况。
