How to check if a string is a rotation of another string in Kotlin

Answer 1

fun isRotation(s1: String, s2: String): Boolean {
    return (s1.length == s2.length) && (s1 + s1).contains(s2)
}

fun main() {
    var s1 = "abbc"
    var s2 = "cabb"
    println(if (isRotation(s1, s2)) "yes" else "no")

    s1 = "abbc"
    s2 = "bbac"
    println(if (isRotation(s1, s2)) "yes" else "no")
}
