Password decomposition

Report a typo

You have the following code:

fun main() {
    var validationResult = false
    var password: String
    while (!validationResult) {
        var password = readln()
        validationResult = password.length > 4
        if (!validationResult) {
            println("Your password should be five or longer characters, please write a new password")
        }
    }
    println("Good password")
}

This program asks for a password, and if it is shorter than 5 characters, it asks again until it receives a password of 5 or longer.

We need to decompose the program to the functions validatePassword() and main(). You already have the main() function.

Your task is to write a password length check in the validatePassword() function. If the password is less than 5 characters, print "Your password should be five or longer characters, please write a new password" and return false as the result of the function.

If the password is 5 characters or longer, print "Good password" and return true.

Write a program in Kotlin
fun validatePassword(password: String): Boolean {
// write your code here

}

// do not change the code below
fun main() {
var validationResult = false
while (!validationResult) {
val password = readln()
validationResult = validatePassword(password)
}
}
