Happy Number | LeetCode 202 | Python Solution

Welcome to my channel!

In this video, we'll be solving the LeetCode problem "Happy Number" (LeetCode 202) using Python.

I'll walk you through two different techniques:
one using the fast and slow pointer approach and the other using a set data structure. This problem is excellent for practicing loops and set data structures.

**Problem Description:**
A happy number is a number defined by the following process:
Starting with any positive integer, replace the number by the sum of the squares of its digits, and repeat the process until the number equals 1 (where it will stay), or it loops endlessly in a cycle which does not include 1.
Those numbers for which this process ends in 1 are happy numbers.

**Topics Covered:**
- Fast and Slow Pointer Technique
- Using Sets to Detect Cycles
- Loops and Conditional Statements
- Step-by-step coding solution in Python
