Here is an interactive problem — Searching Rectangles [](http://codeforces.com/problemset/problem/713/B)

Problem B. -> http://codeforces.com/gym/100488?locale=en

This year googlejam added some interactive problems. I suppose you can take a look there.

You can check these problems from Indonesian National Olympiad in Informatics :

• https://training.ia-toki.org/problemsets/90/problems/467/
• https://training.ia-toki.org/problemsets/91/problems/471/
• https://training.ia-toki.org/problemsets/52/problems/252/
• https://training.ia-toki.org/problemsets/53/problems/255/
• https://training.ia-toki.org/problemsets/2/problems/6/
• https://training.ia-toki.org/problemsets/3/problems/9/

Can we have interactive problems as a tag on codeforces as it will be helpful to search them by tag on problemset and apply various filters along with it in the recently introduced filtering option ?

Codechef December Challenge is full of interactive problems this time :) Link
