Grokking the Coding Interview Patterns in C#

Solution: Decode String

Explore how to decode encoded strings by implementing a stack-based solution in C#. This lesson helps you understand handling nested and repeated patterns by using stacks to track substrings and repeat counts, sharpening your problem-solving skills for coding interviews.

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 valid, ...
