Solution: Decode String

Explore how to decode strings that follow a repeated pattern using a stack-based approach in Go. Learn to manage nested sequences and repeat counts effectively by processing the string character by character. This lesson helps you implement the algorithm to decode strings with brackets and numbers and grasp its time and space complexity.

We'll cover the following...

Statement

Given an encoded string, return its decoded version. The encoding rule follows the pattern: k[encoded string]k[encoded~string] ...
