How to efficiently remove every occurrence of one string inside another

+1
−8

I have two strings and want to remove every occurrence of the second string inside the first one starting from the beginning of the first string and as if each occurrence was removed immediately. I would like to do so in C in a time-efficient way, i.e. probably with the lowest number of comparisons and include/copy actions.

Maybe add examples? The word "immediately" is not clear; maybe best to clarify it with examples. Also... (2 comments)

I suggested an edit that focuses the question on the determination of the output string. Data input and output are not really relevant for that.

Trilarion‭ I have approved your edit as it is clearly better than the initial post (no useless code provided). However, it still sounds like "do my homework for me" as opposed to asking a more targeted question (as suggested in another comment thread).

@Alexei I think that the problem is now quite specific and clear and the solution would fit into an answer. There is not much research and it's a "do my work for me" question, but then all questions are to some extent. We probably need a meta discussion about how much prior effort must be in a question. I think the biggest challenge is making sure a problem is clearly described and not a duplicate on this platform. But maybe we should require more.
