Features leetcode is missing #239
Description
Learning from other similar platforms is important on having a way forward:
- More language support
- better vim keybindings support
- Leetcode is missing optimisation problems, communication problems, interactive problems
- Communication problems is when you solve 2 problems in one. The first time you get some input and you can output something, the second time you get the output from the first time, and you need to get some answer (Codeforces has that)
