📘 LeetCode 91 – Decode Ways

In this short, we’ll decode one of the most classic Dynamic Programming problems — how many ways can a string of digits be translated into letters (A-Z)? This is where DP shines! 💡

We walk you through an efficient JavaScript solution that handles edge cases and overlapping subproblems using bottom-up DP.

🎯 What You’ll Learn:

How to build a DP array for string decoding

Handling '0's and invalid substrings

Optimizing recursive problems using tabulation

🧠 A must-know problem for interviews at FAANG and beyond!
