Bug in a Kotlin Challenge

Question

Something weird happening in a Kotlin Pro challenge. Chapter "Control Flow", section "For Loops"
The challenge statement is in the following: ====================================================== Vertical Text

You need to make a string as input and output it vertically, each letter on a new line.
.
Sample Input:
hello
.
Sample Output:
h
e
l
l
o

Use a for loop to iterate over the letters of the string. ============================================================
If you just print the input horizontally, it already congratulates you as if you have solved the problem

I think the supposed solution would be:
----------------------------------------------------------------------------------------- fun main(args: Array) {
var a = readLine()
for(i in a){
println(i)
}
}
-------------------------------- But the code doesn't run!

Answer 1

Lucas Kliemczak

Yes I already reported this but didn't get any response.

To complete this task just print input value

println(a)

Answer 2

Write code for this question is :-

fun main(args:Array<String>) {
val a = readLine()
if (a != null) {
for (x in a) {

println(x)

}
}
}

Answer 3

Report to sololearn by [e-mail] or use the in-app bug report for suggestion.

Answer 4

You can add " !! " in readLine(), i think like...

fun main(args: Array<String>) {
val input = readLine()!!

for(x in input){
println(x)
}
}

Answer 5

There is no Bug ,I did this code and it worked....
Try it and let me know weather it is working or not.

fun main() {
//print("Enter a string: ")
val inputString = readLine()

if (inputString != null) {
val charArray = inputString.toCharArray()
for (char in charArray) {
println(char)
}
}
}
