What changes are you trying to make? (e.g. Adding or removing code, refactoring existing code, adding reports)

Added code the jupyter notebook of the assignment

What did you learn from the changes you have made?

Already familiar with python

Was there another approach you were thinking about making? If so, what approach(es) were you thinking of?

A more efficient approach is to use dictionaries to count the number each unique charecter. This will have a better time efficiency as dictionary uses hash map and has o(1) time complexity for inserting which makes the algorithm o(n) while the sorting approach is o(nlog(n))

Were there any challenges? If so, what issue(s) did you face? How did you overcome it?

N/A

How were these changes tested?

Using the test inputs given in the notebook

A reference to a related issue in your repository (if applicable)
