Scenario 1: You are a research engineer at a scientific company specialized in optimizing solutions for construction problems. Your team leader assigned you some tasks which require solving mathematical operations. In all tasks, whenever the letter Q appears in a number then you need to replace it with two numerical digits equal to your last two digits of your university ID. For example: ID 17115038 means that Q = 38
