Hi everyone,

Hope you all have a happy new year.

I would like to share with you my last project this year, Backtracking Visualizer.

It's a visualization tool for some backtracking standard problems (Sudoku Generator, Sudoku Solver, N Queens, Knight's Tour), which helps to understand backtracking technique in general and how to use it to solve these problems in particular. It shows and describes all the steps of finding the solution, also gives the option to choose different parameters for each problem.

You can know more about it and visit it from:

Hope you enjoy it and if you have any comments please let me know.

Hi everyone!

I'd like to share with you my new extension, Codeforces Practice Tracker.

Codeforces Practice Tracker helps to track your practice progress in codeforces through time phases, It simply adds new tab to your profile (or any other profile) in this tab you can find data about each time phase.

For each time phase it shows:

  • Number of solved problems.
  • Number of submissions.
  • Hardest (Max Rated) problem you solved.
  • Average of the rates of the problems you solved.
  • Number of contests and virtuals you participated.
  • Statics of submissions.

Note: Gyms problems and unrated problems are only considered in number of solved problems and number of submissions.

More features:

  • Show each phase and compare it with previous one.
  • Skip inactive phases.
  • Change number of days of each phase.

It can be useful also for trainers who want to keep updates about their trainees.

You can download it here: Chrome, Firefox

If you find any bugs, have any comments or suggestions please let me know.

Hope you like it and consider sharing it with your friends. Stay safe.

UPD: This was my first time to create browser extension so I made It just for chrome. I'll provide it for firefox soon, Guess It won't be that hard.

UPD2: It's available now for Firefox, Thanks for your support.

UPD3: There was an argument about whatever it's better to show " the average" of problems rate or "the mean" or "the number of problems solved of each rating separately", so I made an update. Now you can list all solved problems of each phase with their ratings, I think it may help with this issue.

UPD4: For the past few months, Google disabled reviews of chrome extensions so people couldn't rate or leave reviews for any extension, and no one had the chance to rate my extension. Now it's back, so please rate the extension and leave a review. :D
