Step 1: Choose a
Programming Language
The top choices are:
C++
Java
Python
Once you've selected a language, focus
on mastering its syntax, libraries, and
built-in data structures.

C++ STL Tutorials
Step 2:- Understand Time
& Space Complexity
Start with the basics:
constant time O(1)
logarithmic time O(log n)
linear time O(n)
quadratic time O(n²).

Step 3: Learn Key Data
Structures & Algorithms
Data Structures to Learn:
Arrays, Linked Lists, Stacks, Queues, Trees,
Graphs, Heaps, Hashing.
Algorithms to Master:
Sorting (Bubble, Merge, Quick, Heap).
Searching (Binary Search).
Dynamic Programming (Fibonacci,
Knapsack).
Greedy Algorithms (Activity Selection,
Huffman Coding).
Backtracking (N-Queens, Sudoku
Solver).

Step 4: Practice on Competitive Coding Platforms
Coding Platforms:
LeetCode
HackerRank
Begin with solving easy problems,
progress to medium, and finally hard.
Aim to solve problems daily to build
consistency.

Step 5: Revision & Mock
Interviews
Revision:
Keep track of the problems you've solved
and revisit them periodically.
Mock Interviews:
This will help you experience the time
pressure and problem-solving environment
similar to actual interviews.
