Combinatorics is the mathematics of Counting and combining things! In mathematics and computer science, we often counter different kind of counting problems like finding number of possible passwords using 8 characters, finding number of ways n number of computers can be connected in a network, finding the number of IP address possible etc. In all these problems are want to find the answer without enlisting or going through all possible cases. Combinatorics provides us answer to these questions.
In this Video we're going to cover following topics related to combinatorics:
1. Introduction to Combinatorics.
2. Rule of Sum
3. Rule of Product
4. Pigeonhole Principle
5. Inclusion-Exclusion Principle
6. Permutations
7. Combinations
