💡 Notes to users

• Abbreviations and terms used:

  • [SC] stands for 'sample code' (folder containing sample code files).
  • [M] stands for 'manual' (example code which involves manual input, i.e., is not a helper function).
  • [HF] stands for 'helper function'.
  • [ND] stands for 'normal distribution'.
  • Preparation Code refers to code that is included just so you can to view a sample output.
  • Actual Code refers to code required to perform the function.

• If you have difficulties obtaining your desired output, observe the sample input carefully and mimic its structure. If there is a mistake in this repository, please let me know (by submitting an issue with label bug).
