Hello Everyone!
The next day during Week 11 we focused on pimping the Sliding Window technique of course. These problems highlighted bound and condition management for objects in dynamic windows, margins being a key area of concern here. Solving them was like handling insects that run around in the most efficient manner possible.

,Maximum Number of Vowels in a Substring of Given Length
– [maximum number of vowels in any substring of size k]- The Strategy: This he used a sliding window to count vowels in the first substring of length k. Modified it dynamically where the current count is incremented with the next character and the first character of the previous window is deleted, then tested if the character is a vowel.
- The Fun Part: It was visually engaging to see the count of vowels change when a window is shifted which made it like a real-vowel tracker program.

Max Consecutive Ones III (Medium Difficulty)
Given an array A of 0s and 1s, where it is allowed to flip at most k 0s, the task is to find the maximum size of the subarray which only contains 1s.-
The Strategy:
Employed two-pointer technique to increase the size of the window and thereby kept count of the number of
0s. Reduced the size of the window whenever the number of occurred 0’s in the current window was above the count of k, to make sure that the situation was possible. -
The Fun Part:
It was like solving resource allocation problem where one has to flip
0s and at the same time try to make the size of the subarray as large as possible.

The Strategy:
Employed two-pointer technique to increase the size of the window and thereby kept count of the number of
Today’s Events
Dynamic Adjustments:
Both problems involved updating count and boundaries in real time and hence brought out the dynamic view of thinking in sliding window concepts.Practical Applications:
These challenges were close to real life such as tracking vowels in speech analysis or controlling the stream of the transmitted packets by applying certain constrains.Optimization Through Simplicity:
This sliding window approach made these tasks linear time complexity and was powerful examples that using good algorithms were much efficient.
Key Takeaways
Sliding Window Simplifies Traversal:
The sliding windows gained efficient control and optimization of operation on substrings as met in problems such as **Maximum Number of Vowels in a Substring.Two Pointers Manage Constraints:
Max Consecutive Ones III also put emphasis on constant changing of constraints by two-pointer methods.Focus on Incremental Changes:
Specificity is maintained and overwriting is avoided by updating the counts and also the conditions in an incremental manner in both the tasks.
Reflections
The Maximum Number of Vowels in a Substring was a nice problem in sliding window traversal whereas Max Consecutive Ones III had the additional challenge of constraints handling. Altogether these problems highlighted the need to use dynamic window techniques when solving string and array problems effectively.
What’s Next?
The next day, I’ll spend my time solving problems tagged as Sliding Window and Prefix Sum, solving Find the Highest Altitude and Find Pivot Index. These tasks are going to involve the sum of totals with optimization methods for optimal approaches.
So thanking you for joining in the coverage of the Democratic National Convention. We’ve tried to solve the problem, learn from this case, and possibly grow together.
