13:00 - Conclusion
You are given a string s. Simulate events at each minute i:
If s[i] == 'E', a person enters the waiting room and takes one of the chairs in it.
If s[i] == 'L', a person leaves the waiting room, freeing up a chair.
Return the minimum number of chairs needed so that a chair is available for every person who enters the waiting room given that it is initially empty.
In this video, I explain how to determine the minimum number of chairs needed in a waiting room given a sequence of events.
** Approach 1: Basic Looping Logic **
A straightforward method to iterate through the string and keep track of the current number of people and the maximum number observed.
** Approach 2: Fine-Tuned Code **
A more concise and optimized version of the first approach, utilizing a single line to update the count and the maximum number of people in the waiting room.
For a comprehensive understanding and practical demonstration, be sure to watch the entire video. Happy coding!
