Refer tasks.yaml for more accurate instructions

For Players

All the tasks must be zipped in the following structure

- tasks.zip
  - swapper/
    - swapper.py
  - summer/
    - summer.c
    - Makefile
  - sanity/
    - sanity.flag
    - sanity.txt

Make the zip file downloadable from the internet and give the link to pundit

Ex. !tasks submit https://bashupload.com/Nb-Kb/tasks.zip

All the python files must take the testcase input from stdin and print the respective output to stdout.

The flag evaluated solutions should be named task.flag with the contents flag{.*} i.e, the respective flag.
