LeetCode 10: Regular Expression Matching,
one of the most challenging pattern matching problems using Dynamic Programming and Recursion.
You’ll understand how . and * work in regex matching and how to build a DP-based solution from scratch.

💡 Problem Description
Given an input string s and a pattern p, implement regular expression matching with support for . and * where:

. → Matches any single character

→ Matches zero or more of the preceding element

The matching must cover the entire input string (not partial).

📘 Example 1
Input: s = "aa", p = "a"
Output: false
Explanation: "a" does not match the entire string "aa".

📘 Example 2
Input: s = "aa", p = "a*"
Output: true
Explanation: '*' means zero or more of the preceding element 'a'. Repeating 'a' once makes it "aa".

📘 Example 3
Input: s = "ab", p = ".*"
Output: true
Explanation: ".*" means "zero or more of any character".

⚙️ Constraints

1 ≤ s.length ≤ 20

1 ≤ p.length ≤ 20

s contains only lowercase English letters

p contains only lowercase English letters, . and *

Every * in p has a valid preceding character
