What did you learn from the changes you have made?

• How to write python code to solve anagrams problem in O(n) of complexity

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

• Another approach is just sort word_a and word_b, then compare them, if matched, then the words are anagrams. But this approach is slightly more complex than the given one with O(nlogn) of complexity.

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