Question

有没有大神可以帮忙求通项。

Answer 1

N = [1]
i = 0
a = 1
print("(", i, ", ", 0, ") =>", N)

while i < 5:
    s = [x + a for x in N]
    N = N + s
    print("(", i, ", ", a, ") =>", N)
    i = i + 1
    a = a * 2
    

只算到了5，可以修改成你要的范围。下面是输出：

( 0 ,  0 ) => [1]
( 0 ,  1 ) => [1, 2]
( 1 ,  2 ) => [1, 2, 3, 4]
( 2 ,  4 ) => [1, 2, 3, 4, 5, 6, 7, 8]
( 3 ,  8 ) => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]
( 4 ,  16 ) => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32]
