Solution: Decode String

Explore how to decode encoded strings that include nested and repeated patterns by implementing a stack-based algorithm. This lesson teaches you to manage substrings and repeat counts using stacks, enabling you to reconstruct the original string from its encoded form with proper handling of nesting and sequence.

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 string is always ...
