// Current imperative looping approach: 

// for (for-each in some languages):
//   do something with every element of a collection 
//   (including, known number of times ala sequence)

// for (item in collection) {
//     // code, that typically references item
// }


// Question: how to loop until a *condition* is met?

























// Conditional looping: continue while a Boolean expression is true

// while (condition) {
//     // code
// }

// val num = 7
// while (num % 2 == 1) {
//     println("$num is odd")
// }

// Questions:
// 1. Similar to something we've seen with recursion? Same?
// 2. Why does this feel limiting?






















// import khoury.input
// import khoury.isAnInteger

// fun getEvenNum(): Int {
//     while (true) {
//         println("Enter an even number")
//         val typed = input()

//         if (isAnInteger(typed)) {
//             val num = typed.toInt()

//             if (num % 2 == 0) {
//                 return num
//             }
//         }
//     }
// }

// val myNum = getEvenNum()
// println("Even number: $myNum")






















// do {
//     // code
// } while (condition)

import khoury.input

do {
    println("Are we there yet?")
    val thereYet = input()
} while (thereYet != "I give up")

println("😈")


// Questions:
// 1. What's the difference (while vs do-while)?
// 2. How do I know when to use for vs while/do-while?
