Greater Toronto Programming Competition Individual Round (Mirror)

The Greater Toronto Programming Contest was an in-person multi-school competition with both an individual and team round held in April.

It was organized by St. Robert Catholic High School, with help from William Lyon Mackenzie CI for problem setting and hosting the contest on their judge.

This contest will NOT be rated, as it is a mirror.

Each problem is worth 100 points, with extra points available for early submissions and first-try ACs (following standard ECOO format).

Listed below is some advice for contests:

  • Remove all extra debugging code and/or input prompts from your code before submitting. The judge is very strict — most of the time, it requires your output to match exactly.
  • Do not pause program execution at the end. The judging process is automated.
  • You should use stdin / stdout to perform input / output, respectively.
  • It is guaranteed that all the problems will be solvable with C++, Java and Python.
  • Python users are highly recommended to use PyPy 2/3 over Python 2/3 when submitting.
  • Read carefully, and try to attempt all the problems.
