[walleeva2018]

If given the permission i could make bengali tutorials for at least 100+ problems within a month , many of them already have tutorials in English though.

@walleeva2018 If you are still working on this, propose a PR when you add a new translation or editorial in Bangla. Remember to create individual PRs for each problem. I am closing this issue since it doesn't help anybody in anyway knowing you want to do some work on some problems.
