Info

Here are six practice problems for the first-ever CS50x Coding Contest. Familiarize yourself with HackerRank's user interface so that you're ready for the actual contest, which starts on Friday, 29 July 2016, and ends on Sunday, 31 July 2016. The actual contest will have more than six problems, some of which may be a bit harder! 0:-) See hackerrank.com/faq for answers to FAQs.

Rules

  • Please refrain from discussing strategy during the contest.
  • All submissions are run through a plagiarism detector. Any case of code plagiarism will disqualify both users from the contest.
  • You can also code using our interface, which currently supports over 40 major languages. Learn about our environment and time limits here. If you are not yet familiar with our platform, check out Solve Me First to acquaint yourself with I/O.
  • HackerRank admin decisions are final.

Scoring

  • Each challenge has a pre-determined score.
  • Your score for a problem depends on the number of test cases your submission successfully passes.
  • A participant's total score is the sum of the scores earned for each problem attempted. If you submitted more than one solution for a problem, only your highest score achieved will be used in this calculation.
  • Participants are ranked by score, with the cumulative time taken (between the contest's start time and the time of your correct submission) used to break ties.
