#LSPPDay08
- Revised the LC problems solved sofar.
- Looked into LeetCode#21 "Merge Two Sorted Lists".
- Also learnt how to deploy on Kubernetes, and interact with clusters with a sample app (and made docs)

#LSPPDay07
Solved Leetcode #20 "Valid Parentheses"
Used stack to match brackets and ensure correct opening-closing order.
(lowkey proud for taking no help this time B) )

#LSPPDay06
Solved Leetcode #14 "Longest Common Prefix"
Tried two approaches: sorting strings and comparing first & last, and horizontal scanning by shrinking the prefix with each string.

#LSPPDay05 Solved leetcode#13 "Roman To Integer". Simple if else logic was applied.
+ Learnt about Docker network and Kubernetes architecture, and the need for orchestrator. Made documentation too.

#LSPPDay04 Solved leetcode#9 "Palindrome Number". Reversed the number and compared with original, and in another approach, reversed a half and compared it with the other half. Solving easy problems before tougher ones. #60DaysOfLearning2025 #LearningWithLeapfrog

#LSPPDay03
Solving leetcode#3 "Longest Substring Without Repeating Characters" by bruteforce and sliding window. Also figured out the solution for #2 from yesterday's leftover.

#LSPPDay02
Solving leetcode#2 "Add Two Numbers". Noobie brain might need another day or two.
Learnt about docker, containerization and related commands as a sidequest - to make up for the incomplete main quest.

Day 1 feels like yesterday, but we've come to the last day of #60DaysOfLearning2024. Reflecting on the past 60 days, they've enriched my understanding significantly. Yet, the true standout is the realization that consistency is the key. So glad I opted in for this.

[Safal @Safal2002]

#LSPPDay60: Completed two chapters from "Preprocessing for Machine Learning" course. Learnt about Preprocessing techniques, Pd column type conversion, log norm, Std. Scaling & their impacts on distance-based algorithms.

[Safal @Safal2002]

#LSPPDay59: Learnt about the pros, cons & working of the DBSCAN algorithm (Density Based Spatial Clustering of Applications with Noise) for cluster analysis in dataset. This time with pen and paper on a small set of pts.

#LSPPDay54: Made some corrections on yesterday's code, implemented a limited DataLoader, & wrote code to visualize the losses and accuracies and evaluate on test data. Came across a new set of bugs to ponder on tomorrow😛
