Correct Space Complexity and Optimized Solution for LeetCode 383: Ransom Note

[Tesfamichael12]

How are you doing Greg,

I've identified an issue with the current solution for LeetCode 383: Ransom Note. The existing solution did not accurately reflect the correct space complexity, which I have now corrected. Additionally, I've optimized the code to make it more clear and concise keeping the same logic ofcource(I used the Counter function instead of a manual for loop to populate the hashmap.).

Changes:

-> Renamed counter to hashmap to undo any confusion in other languges
-> Corrected the space complexity analysis in the comments.
-> Refined the code for better readability and efficiency.

I also want to mention that Algomap has been incredibly useful, and I've been actively using it to improve my problem-solving skills. Thank you for this great resource!

Looking forward to your feedback.

Best regards,
Tesfamichael
