In codechef can we find problems related to a particular topic by searching in practice section?
Use ‘Ctrl+F’ to search tags like dfs , bfs, dp , djikstra … etc.
Also check this , where topicwise sample problems are given. https://www.codechef.com/certification/prepare#foundation
Yes, there is a “tag” section for it. At the homepage, look at your left. You will see “Search problem by tag”. Enter the tag (topic like seg-tree, problem setter name etc.) for searching, else all tags are visible there.
Mind one thing, only those problems are searchable by this method which have an editorial (and hence have been tagged).
If this doesnt suffice, then googling is way better option, at least in my opinion
Lol. 54 sec XDXD
