Search 1D array with all the indices of the matched elements

[Zekasa]

Hi,

 the "Search 1D array" function returns only the index of the fist item found. However some times, it is needed to get all the indices of the elements that match the element the we are searching for. I think it will be nice if this vi returns all the indices that match the element we are looking for.

   

to become like this

You really need to be more careful posting code like that so soon after a coding challenge! 🙂

So Donald Knuth spent a lot of time thinking through and documenting the provably best ways to search.

Would an "ideal" version of "return matching indices of array" be structured like a Knuth-search?

The Search 1D Array assumes your array is not sorted.  Therefore, you are left with only being able to do a simple linear search.

Bingo. If you want to search with a sorted assumption, check out

     vi.lib\Array\Search Sorted 1D Array.vim

in LV 2019 or later. It's not in the palettes... yet. 😉
