Some problems are not solved by trying once —
they are solved by trying, failing, going back, and trying smarter

That powerful problem-solving pattern is called Backtracking, and in this video I explained it in the easiest possible way with intuition, diagrams, and real problem patterns — not confusing theory.

If recursion made sense to you but complex search problems still feel scary, this lecture will connect all the dots.

WHAT YOU WILL LEARN IN THIS VIDEO
* What Backtracking really means in problem solving
* The Try → Undo → Retry strategy
* Backtracking vs Recursion difference
* How recursion is used inside backtracking
* State Space Tree concept explained visually
* Core components of Backtracking algorithm
– choice
– constraints
– goal condition
– recursion step
– undo step (backtrack)
* What is Pruning and why it is critical
* How pruning saves exponential time
* Where Backtracking is used in real problems
* Famous Backtracking problems overview
* Time complexity reality of backtracking
* When Backtracking should NOT be used
WHEN NOT TO USE BACKTRACKING

Top interview problems based on Backtracking:
* N-Queens
* Sudoku Solver
* Rat in a Maze
* Permutations & Combinations
* Subset generation
* Word Search

Interviewers don’t just check code — they check whether you understand state reversal and pruning logic.
