问题描述
解释如何将地图，序列等转换为各种序列和集合，但不说如何将地图转换为交替的键和值的序列。这里有一种方法：
Answers to this question explain how to convert maps, sequences, etc. to various sequences and collections, but do not say how to convert a map to a sequence of alternating keys and values. Here is one way:
(apply concat {:a 1 :b 2})
=> (:b 2 :a 1)
一些人可能天真地认为会产生相同的结果，不要，包括传递映射到 vec ，向量， seq ，序列， into [] ， into c>和 flatten 。
Some alternatives that one might naively think would produce the same result, don't, including passing the map to vec, vector, seq, sequence, into [], into (), and flatten. (Sometimes it's easier to try it than to think it through.)
有比 apply concat 更简单的东西吗？
Is there anything simpler than apply concat?
推荐答案
您也可以执行
(mapcat identity {:a 1 :b 2})
或
(mapcat seq {:a 1 :b 2})
