This video explains a challenge to create a program in Scala that uses an array of numbers. The challenge includes writing functions to find the average of all numbers in the list and the min and max values.
(light music)…- [Instructor] Are you ready for the next challenge?…There was a lot of content in this section.…In this challenge I want you to create a new project…in the Scala IDE.…Add a Scala app.…In that app create a function that will find the average…of an array of numbers.…Also write two more functions, one to find the minimum…inside the array and one to find…the max value inside the array.…Create an array with 10 values then use the functions…you created to print out the results…of the average, sum, min, and max.…
Don't forget to use some of the tips and tricks…we learned along the way.…For this challenge I estimate it'll take about 15 minutes.…When you're done come back and take a look…at the solution video where I walk you through…my thought process along the way.…
