Sequence Reductions
| Difficulty: | Medium |
| Topics: | seqs core-functions |
Write a function which behaves like reduce,
but returns each intermediate value of the reduction.
Your function must accept either two or three arguments,
and the return sequence must be lazy.
 | (= (take 5 (__ + (range))) [0 1 3 6 10]) |
| (= (__ conj [1] [2 3 4]) [[1] [1 2] [1 2 3] [1 2 3 4]]) |
| (= (last (__ * 2 [3 4 5])) (reduce * 2 [3 4 5]) 120) |
