Interactive problems have become a very popular problem type in various judges, and appear very frequently on different coding contests. However, it is very inconvenient for users to search problems for practice unless u look closely upon every problem in the problemset, which is impossible to do given that there are now 50 pages of problems -.-
Therefore, I believe an interactive problem tag should be added to distinguish them from the traditional problem types.
Sorry for bad grammar, idk English
Wholeheartedly agree with this, given that there is already a “constructive” tag for another specific class of problems. Having a binary search tag does not count! :D
