No Recursion, No Table, Still DP? My Shift From Brute Force to Intuition

The author reflects on their journey with Dynamic Programming (DP) and their shift in thinking from a recursive approach to a more intuitive one.
Initially, the author thought DP involved recursion, memoization, tabulation, and space optimization, but a recent problem challenged this pattern.
The problem involved finding the maximum of the minimum for each window size in an array.
The author's initial brute-force solution failed, leading them to consider a new perspective.
By fixing elements instead of window sizes, the author was able to determine the range of window sizes where an element is the minimum.
This approach utilized monotonic stacks to optimize the solution.
The author realized that DP is more about avoiding repeated work and finding efficient ways to reuse calculations.
They acknowledge that DP can appear in various forms, such as using stacks, loops, or different problem-solving approaches.
The author started noticing patterns like utilizing prefix sums, monotonic stacks, reevaluating nested loops, and reusing information.
They emphasize that DP is not just about following a set formula, but about approaching problems cleverly.
The author humorously reflects on their previous perception of DP and how they have evolved to focus on smarter thinking over traditional methods.
Despite facing challenges and TLE errors in the process, the author appreciates the growth and change in their problem-solving mindset.
The author invites others to learn more about the problem that altered their approach.
Overall, the journey showcases a shift from rigid DP methodologies to a more adaptable and creative problem-solving mindset.
DP is portrayed as a means of avoiding redundant work and approaching challenges in innovative ways.
The author concludes by highlighting the importance of thinking strategically and efficiently in problem-solving endeavors.
