# Recursion, Backtracking and Dynamic Programming in Java Download

Competitive Programming with Common Interview Questions (Recursion, Backtracking and Divide and Conquer Algorithms)

#### What you’ll learn

- Understand recursive approaches
- Understand backtracking
- Understand dynamic programming
- Understand divide and conquer methods
- Implement 15+ algorithmic problems from scratch
- Improve your problem solving skills and become a stronger developer

#### Requirements

- Basic Java

#### Description

This course is about the fundamental concepts of algorithmic problems focusing on **recursion**, **backtracking, dynamic programming **and **divide and conquer **approaches. As far as I am concerned, these techniques are very important nowadays, algorithms can be used (and have several applications) in several fields from software engineering to investment banking or R&D.

**Section 1 – RECURSION**

- what are recursion and recursive methods
- stack memory and heap memory overview
- what is stack overflow?
- Fibonacci numbers
- factorial function
- tower of Hanoi problem

**Section 2 – SEARCH ALGORITHMS**

- linear search approach
- binary search algorithm

**Section 3 – SELECTION ALGORITHMS**

- what are selection algorithms?
- how to find the k-th order statistics in O(N) linear running time?
- quickselect algorithm
- median of medians algorithm
- the secretary problem

**Section 4 – BIT MANIPULATION PROBLEMS**

- binary numbers
- logical operators and shift operators
- checking even and odd numbers
- bit length problem
- Russian peasant multiplication

**Section 5 – BACKTRACKING**

- what is backtracking?
- n-queens problem
- Hamiltonian cycle problem
- coloring problem
- knight’s tour problem
- Sudoku game

**Section 6 – DYNAMIC PROGRAMMING**

- what is dynamic programming?
- knapsack problem
- rod cutting problem
- subset sum problem
- Kadan’s algorithm (maximum subarray)
- longest common subsequence (LCS) problem

**Section 7 – OPTIMAL PACKING **

- what is optimal packing?
- bin packing problem

**Section 8 – DIVIDE AND CONQUER APPROACHES**

- what is the divide and conquer approach?
- dynamic programming and divide and conquer method
- how to achieve sorting in
*O(NlogN)*with merge sort? - the closest pair of points problem

**Section 9 – COMMON INTERVIEW QUESTIONS**

- top interview questions (Google, Facebook and Amazon)
- anagram problem
- palindrome problem
- trapping rain water problem
- egg dropping problem
- dutch national flag problem

In each section we will talk about the theoretical background for all of these algorithms then we are going to implement these problems together from scratch in Java.

Finally, **YOU CAN LEARN ABOUT THE MOST COMMON INTERVIEW QUESTIONS** (Google, Microsoft, Amazon etc.)

Thanks for joining the course, **let’s get started!**
