Today I learned one of the most useful Git concepts: Cherry-Pick.
A simple but powerful way to handle the kind of messy commit situations interns often create (Not me ๐
).
Thanks @Hiteshdotcom Sir for explaining it so clearly! ๐

Big lesson:
If a problem says โfor each element except itselfโ,
think two-pass strategy:
prefix + suffix.
Precompute once.
Reuse smartly.
#Algorithms #ProblemSolving #DevLearning
Big insight:
If your running sum becomes negative,
it no longer helps future results.
Reset early. Maximize later.
This pattern shows up in profits, DP, and sliding windows.
#Algorithms #ProblemSolving #DevLearning
Big lesson:
When you need max difference,
track the smallest value before the current index.
Greedy + single traversal = clean solution.
#Algorithms #ProblemSolving #DevLearning
Big takeaway:
When you see pair + target,
think complement + hash map.
Trade space for time.
That pattern shows up everywhere.

โข Amazon S3 = reliable object storage
โข Bunny CDN = much cheaper for bandwidth-heavy files
So many setups use:
๐ Storage + CDN layer together
Also experimented with exposing local apps via public IP tunneling

Big lesson:
Whenever a problem asks for a range in sorted data,
think in terms of lower and upper bounds.
Binary Search is really about shrinking space intelligently.
#Algorithms #ProblemSolving #DevLearning
Recursive โ elegant & expressive
Iterative โ controlled & stack-safe
Same algorithm. Different tradeoffs.
Understanding both builds deeper problem-solving intuition.

Big lesson:
When traversal stays the same but output changes, you probably just need state control, not a new algorithm.
Small flags. Big clarity.

Key rule:
If one subtree is null โ follow the other one.
Only take min when both exist.
Lesson:
In recursion, base cases decide everything.
#Recursion #ProblemSolving #DevLearning
Push before going deeper.
Pop when coming back.
State management is everything in path problems.
Lesson:
When asked for all results, think backtracking immediately.
#Recursion #Backtracking #ProblemSolving #DevLearning
Big lesson:
In recursion, you either build the answer forward or shrink the problem backward.
Choosing the right mental model makes tree problems feel much cleaner.
#Recursion #ProblemSolving #DevLearning
Big lesson:
2D problems become easier when you control movement explicitly.
Itโs not nested loops, itโs layer-by-layer traversal with discipline.
Clean boundaries = clean logic.
#ProblemSolving #DataStructures #DevLearning
Big lesson:
In BSTs, violations in sorted order are signals.
Traversal invariants arenโt just theory, theyโre practical tools for recovery and debugging.
#TreeProblems #ProblemSolving #DevLearning
Big lesson:
Balancing doesnโt always mean fixing locally.
Sometimes, reconstruction with the right invariants is simpler, cleaner, and more reliable than incremental tweaks.
#TreeProblems #ProblemSolving #DevLearning
The trick: replace the node with its inorder successor (min in right subtree), then delete that successor.
Lesson:
Deletion is really about preserving structure, not just removing values.
#TreeProblems #ProblemSolving #DevLearning
Viterbi is a great example of classic algorithms solving real-world problems at scale.
If youโre into data, maps, or system design, this is worth learning deeply.
