import java.util.*

    val scanner = Scanner(System.`in`)
    val str = scanner.next()

    var aFlag = false
    var bFlag = false
    var cFlag = false
    if (str.length == 3) {
        str.forEach {it ->
            run {
                if (!aFlag && it == 'a') {
                    aFlag = true
                }
