Company: Apple
Role: Software Engineer
Category: Coding & Algorithms
Difficulty: medium
Interview Round: Onsite
Overview: This question evaluates understanding of data structure design, specifically simulating queue (FIFO) behavior using only stack (LIFO) operations. It is commonly asked in coding interviews to assess amortized time complexity reasoning and the ability to translate between abstract data structure interfaces, testing practical algorithmic implementation skill.
