Question

Answer 1

from functools import reduce

N,M = map(int, input(">>>").split())
data = list(map(int, input(">>>").split()))

I, MUL = 0, 0
for i in range(N):
    if i <= N - M :
        s1 = reduce(lambda x, y: x *y, data[i:i+M], 1)
        if s1 > MUL:
            I = i + 1
            MUL = s1


print(MUL, I)
