编程求解：数字币面值累加不同结果及合数数量

```python from itertools import combinations # 判断一个数是否为合数 def is_composite(num): if num < 4: return False for i in range(2, int(num0.5) + 1): if num % i == 0: return True return False # 读取输入 n = int(input()) values = list(map(int, input().split(','))) k = int(input()) # 生成所有可能的组合并计算累加和 sums_set = set() for comb in combinations(values, k): current_sum = sum(comb) sums_set.add(current_sum) # 统计不同结果的个数 total_different_sums = len(sums_set) # 统计不同合数的个数 composite_count = 0 for s in sums_set: if is_composite(s): composite_count += 1 # 输出结果 print(f"{total_different_sums},{composite_count}") ``` ######[AI问答 | 227点数解答 | 2025-11-22 20:47:55]
