第一题，不知道问题在哪
import sys if __name__ == "__main__":
    line1 = sys.stdin.readline().strip()
    n, k = list(map(int, line1.split()))
    line = sys.stdin.readline().strip() # 把每一行的数字分隔后转化成int列表  values = list(map(int, line.split())) print(n,k,values) def cal(n, k, values):
        ans = -1  if k == n: return 1  res = sum(values[:k])

                ans = head + 1  head += 1  tail += 1  return ans print(cal(n, k, values))
