Add page containing partially complete solutions

[singhpratyush]

As of now, it is difficult to look for solutions one can improve in the repo. It would be good to have a page(s) on gh-pages where we can see all the problems with WA and TLE.

• [ ] Issue Title is in form Problem Code (Contest Code) [Language]
• [ ] I ensure I'm Eligible as per ECR.
• [ ] I got AC for this problem when the contest was live. (Not necessary, but appreciable).
• [ ] I have checked that my solution is passing on Problem (in case you make some changes).
• [ ] I will send my PR only after I'm assigned to this issue by any maintainer.
• [ ] I ensure that I'm not assigned to more than 2 issues.
  • [ ] Assign this issue to me (I want to work on this).

It's not necessary for all for points to be checked, we will look at what is required once you open an issue.

@Monal5031 Can you work on this?

[Monal5031]

@singhpratyush @aashutoshrathi I have an idea, we can create a label need improvement for PRs and can give link in README itself.

[aashutoshrathi]

@Monal5031 But this will link it to PRs, not files, Right?

[Monal5031]

@aashutoshrathi Yes, but we already information about the contests in PRs, if you want we can link it to issues where even the links of contests are mentioned.
