1
Patterns & Sequences: The Brain's Filter
Interview Dossier Attached
Logic is not memorizing; it's decoding. Learn the 5-step template (Observe, Check, Hypothesis, Verify, Answer) to solve any number or symbol sequence without guessing.

2
Counting & Combinations: Avoiding Guesswork
Master the fundamental counting principle. Learn when to multiply (independent choices) versus when to add. This is the foundation for time complexity and space analysis.

Junior Pattern
Guessing the number of pairs by eye. Senior (Elite)
Using the n(n-1)/2 formula for pair counting.Architectural Insight
Architectural analysis.
3
IF / THEN Logic: The Decision Engine
Interview Dossier Attached
Programs are just trees of decisions. Learn why the order of conditions (strictest first) is the most common source of senior-level logic bugs.

4
Arithmetic & Parity: Speed Shortcuts
Learn parity rules (Even/Odd) and divisibility shortcuts. Use these to verify your algorithm's correctness without calculating huge numbers.
5
Problem Decomposition: Plain English First
Never jump to code. Learn to break 'impossible' tasks into 4 simple questions: What is given? What is asked? What are the steps? What is the result? If you can't explain it simply, you don't understand it.
6
Arrays: Indexing & Traversal Physics
Interview Dossier Attached
Go beyond 'a list of things'. Master 0-based indexing and the logic of visiting every 'box' in memory. This is the entry point to all advanced data structures.

7
Linear Search & The Stop Condition
Understand the 'Stop' logic. Learn how to verify that an element is NOT present only after a full scan. This builds the foundation for more complex search optimizations.
Check each box -> If target found, stop -> If end of road, return 'Not Found'.8
Two-Pointer Strategy: Optimized Movement
Learn to move two 'markers' simultaneously. This powerful technique solves pair-finding and distance problems in half the time of a standard nested loop.
9
Frequency Maps: Memory for Performance
Learn to 'remember' what you've seen. Frequency counting using HashMaps (or Objects) is the secret to solving 80% of 'Easy' and 'Medium' LeetCode problems instantly.

Sorting Logic: Selection & Order
Interview Dossier Attached
Master the 'Find, Compare, Swap' cycle. Understanding how a list becomes ordered step-by-step is crucial for mastering Binary Search and Divide-and-Conquer later.
