LLD question I keep asking while building in Spring: if this requirement changes tomorrow, how many classes do I have to touch?
#LowLevelDesign #SpringBoot #BackendDev #LearningInPublic
LLD made me stop asking "which annotation do I use?" and start asking "which class should own this responsibility?"
Spring got a lot less confusing after that.

#CPlusPlus #LowLevelDesign #InterviewPrep
Implement Stack using Queues – exact question asked at @HashedIn by @Deloitte
Single-queue C++ solution:
• push: O(1) – just add to back
• pop: O(n) – rotate all but the top element to maintain LIFO
• top / size / empty: O(1)
Beats 100% runtime on LeetCode.

What’s your preferred approach — one queue or two queues for amortized O(1)?
