Swift version: 5.4
The easiest way to find the largest of three numbers is to use the
max() function with as many parameters as you want to check, like this:
let first = 10 let second = 15 let third = 18 let largest = max(first, second, third)
If you wanted, you could also just call
max() twice, like this:
let largest = max(max(first, second), third)
