Specimen Round 1 Practice Paper

The following Round 1 Practice Paper contains 10 questions (as per the real thing) with an intended time limit of 40 minutes. Don’t forget that your code should not include any prompts with your inputs e.g. to input an integer, you might write in python
num = int(input())

When you start in hackerrank, on Q1 you will need to set your language used in the top right hand corner of the code editor e.g. to python3.

Round 1 will be a 40 minute activity for pairs (or solo) sharing a single computer. For younger students please note that hackerrank has a minimum 13+ sign-up requirement. Some schools have configured some team hackerrank accounts (pctcTeam1@myschool…. ) for them to use.

2018 Problems (Round 2 Style)

The 2018 competition has now ended and the problems are available for on-going review or practice. Please note that the format has now changed slightly and the final (Round 2) will be sat in teams of three with students no longer splitting into two sub-groups.

On the right of the question definition you can see a “more” link. Click this link and you can download the test cases that were used to mark the challenge. Enjoy!

Round 2 Specimen Problems

We have added these specimen problems to a practice competition site so that your teams can experience the competition environment. We will not be uploading the question text themselves to the competition site to maintain security for the main event so, likewise for the simulation, the questions are below and the submissions can be entered once a sign-up for the practice ‘contest’ has been activated.
