Step 1 : Open https://mirror.codeforces.com/ & enter (log in) with your Codeforces username.

Step 2 : Select the Contests option from the navigation bar.

Step 3 : Select the contest you want to take part in & then click the Register button. When the contest is about to start at the scheduled time, you will get an option to Enter the arena on the same page.

Step 5 : Select the Problem you want to attempt.

Step 6 : After understanding the problem, Switch to your offline/online IDE ( like VS Code ) and write the code to solve the Problem.

Step 7 : Once you are done writing the code & running it on the given test cases, Now you have to submit the code file.
