00:00 - Introduction to dataset and Question
01:45 - Scope 1: Concatenate the number of occurrences followed by the character
05:15 - Scope 2: Limit repetitions to at most 9 times
08:20 - Scope 3: Maintain the order of characters
14:00 - Conclusion

You are given a string word. You are asked to compress the string using a specific algorithm.

Find the maximum occurrence of each word and append the count before each character of the string

** Scope 1: Concatenate the number of occurrences followed by the character **
We start by counting the occurrences of each character in the string. Concatenate the count and the character to form the compressed string.

** Scope 2: Limit repetitions to at most 9 times **
Enhance the algorithm to ensure no character count exceeds 9 in the compressed format. Split counts greater than 9 into multiple segments.

** Scope 3: Maintain the order of characters **
Modify the algorithm to preserve the order of characters as they appear in the original string. Count consecutive characters up to a maximum of 9 and append to the result.

This step-by-step approach will help you understand how to tackle similar problems and implement efficient algorithms in Python. Whether you're preparing for coding interviews or just looking to improve your coding skills, this video has something for you!

For a comprehensive understanding and practical demonstration, be sure to watch the entire video. Happy coding!
