私は単純な Enum.drop_while のこれらの 2 行を試しました ... 十分に簡単に思えますが、なぜそれらが異なる結果になるのか理解できません:
iex(6)> 1..100 |> Enum.drop_while(fn(x) -> rem(x,10) == 0 end)
[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, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42,
43, 44, 45, 46, 47, 48, 49, 50, ...]
iex(7)> 1..100 |> Enum.drop_while(fn(x) -> rem(10,x) == 0 end)
[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, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43,
44, 45, 46, 47, 48, 49, 50, 51, 52, ...]
助けていただければ幸いです。
