Master Linear Recursion 🔥 | from Brute force to Advanced| Java | Python | C++

In this video, we learn the Linear Recursion pattern from scratch and solve two of the most important beginner recursion problems — Factorial and Palindrome Check. We start by understanding how recursion works internally, how function calls move inside the call stack, and how answers are calculated during recursive execution. We also learn the difference between Functional Recursion and Parameterized Recursion, and understand when to use each approach. Problems solved in this video: Factorial Palindrome Number For each problem, we cover: Iterative approach Converting iterative solution into recursion Recursive intuition Dry run and call stack visualization Functional recursion Parameterized recursion Time and space complexity In this video, you will learn: What is Linear Recursion How recursive calls work internally Base case and recursive relation How to identify recursive problems Difference between Functional and Parameterized Recursion How to convert loops into recursive calls Two Pointer to Recursion conversion Recursive thinking for coding interviews Mastering linear recursion will help you later in: Backtracking Dynamic Programming Trees & Graphs Divide and Conquer Mastering this pattern will help you solve a wide range of optimization problems efficiently.
