4๏ธโฃ Linked Lists
โ Learn traversal, reversal, cycle detection
โ Key problems: Detect Cycle, Merge Two Sorted Lists
5๏ธโฃ Stacks & Queues
โ Infix to postfix, parentheses validation, monotonic stack
โ Problems: Valid Parentheses, Next Greater Element
6๏ธโฃ Recursion & Backtracking
โ Subsets, Permutations, N-Queens
โ Key skill: build solution tree and backtrack correctly
7๏ธโฃ Binary Search & Search Problems
โ Classic problems: Search in Rotated Array, Koko Eating Bananas

โ Practice shortest path, connected components, cycle detection
1๏ธโฃ1๏ธโฃ Dynamic Programming (DP)
โ Start with 1D DP (Fibonacci, Climbing Stairs)
โ Move to 2D DP (Knapsack, LCS, Grid Paths)
๐กPractice on LeetCode, Codeforces, GFG. Use patterns, not memorization. | 125 |

| 8 | The gap between what we want and what we achieve is filled with consistent effort, dedication and discipline.
We all have dreams, goals, and aspirations but wishing for them alone is never enough. Every day presents us with a choice... we can continue procrastinating, making excuses and staying within the comfortย or we can stay committed to our goals with dedication and discipline
Success is rarely the result of a single big action. It is built through small, consistent efforts repeated day after day, even when motivation is low. The decisions we make today shape the reality we live tomorrow.
The distance between our dreams and our achievements is not measured by luck or talent alone... it is measured by our willingness to stay dedicated when the journey becomes difficult.
Our future is determined by what we consistently choose: comfort or commitment. ๐ทโจ | 157 |
