Harry and Oscar are working on a project where they need to manage a line of tasks that need to be executed in the order they were added. Muhammad suggested a data structure to use. Which data structure did Muhammad likely suggest?

• Hash table

• Stack

• The data structure typically used to manage tasks in the order they were added is a linked list or an array.

• Binary tree

Emily is working on a project where she needs to choose the most efficient algorithm. Arthur suggests using the Big O notation. What is the purpose of the Big O notation in this context?

• To measure the physical size of data in Emily's project

• To determine the color of an object in Emily's project

• The purpose of the Big O notation is to describe the performance or complexity of an algorithm in Emily's project.
