Solution: Decode String

Explore how to decode strings encoded with a pattern involving nested brackets and repeat counts by applying a stack-based approach. Learn to process each character methodically to manage nested and sequential encodings, enabling you to reconstruct the decoded string accurately from inside out.

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], where the encoded stringencoded~string is repeated exactly kk times.

Note: The kk is guaranteed to be a positive integer.

Assume that the input ...
