# Hints ## 1. Determine how long it takes to mix a juice - Julia has no `switch` statement, in contrast to many other languages. - The `if` ... `elsefif` ... `else` syntax was covered in the Conditionals concept. ## 2. Replenish the lime wedge supply - A `while` loop can run until you have enough lime wedges. - The `popfirst!()` function was covered in the Vectors concept. ## 3. List the times to mix each order in the queue - Looping over a vector is easy with `for` ... `in`. - Building a new vector could use `push!()`, which was covered in the Vectors concept. - Later in the syllabus we will explore various other ways to do this in Julia. ## 4. Finish up the shift - See task 2.
