Day 50 of my DSA grind - Wrapped up the Min Stack problem today. The ArrayList version was pretty straightforward, and I used a tutorial to understand the optimised stack-based approach.

@ApnacollegeX Today I explored ArrayList — a dynamic array that grows as needed. Loved how it simplifies working with collections compared to regular arrays! #Java #CodingJourney #100DaysOfCode #buildinginpublic

Today I learned something funny: Stack & Queue can be best implemented using LinkedList, but in Java, Stack uses Vector. Why? Because Stack is a very old class from JDK 1.0 (1995). Back then, Java didn’t have ArrayList (added in JDK 1.2) and the only resizable array was Vector.
