问题描述
如果我有两个集合，我该如何将它们压缩在一起?
If I have two collections, how might I zip them together?
with [1,2,3] as nums, ['a', 'b', 'c'] as letters
... wat do? ...
return zipped // [{a: 1}, {b: 2}, {c: 3}]
推荐答案
可能无法动态分配地图键(例如，使用 letters 中的项目).但是这个查询将返回类似于你想要的东西(使用集合而不是地图):
It may not be possible to dynamically assign map keys (e.g., using the items in letters). But this query will return something similar to what you want (using collections instead of maps):
WITH [1,2,3] as nums, ['a', 'b', 'c'] as letters
RETURN EXTRACT(i IN RANGE(0, LENGTH(nums) - 1) | [letters[i], nums[i]]) AS result;
结果是:
[["a",1],["b",2],["c",3]]
