Decode the Coding Interview in Go: Real-World Examples

DIY: Insert, Delete, and GetRandom in O(1)

Explore how to develop a data structure in Go that supports Insert, Remove, and GetRandom operations all executing in O(1) average time. This lesson helps you understand key concepts behind efficient algorithm design and prepares you to solve coding challenges similar to those in Amazon interview questions.

We'll cover the following...

Problem statement

Implement a set data structure that can perform the following operations:

  • Insert(data): This function should insert data into the set (if the set does not contain it already). It should return false if the data already exists in the set. Otherwise,
