How to pad a string on both sides in Kotlin

Answer 1

fun padBoth(str: String, totalLength: Int, padChar: Char = ' '): String {
    if (str.length >= totalLength) return str
    val padTotal = totalLength - str.length
    val padLeft = padTotal / 2
    val padRight = padTotal - padLeft
    
    return padChar.toString().repeat(padLeft) + str + padChar.toString().repeat(padRight)
}

fun main() {
    println("'" + padBoth("Kotlin", 11) + "'")
    println(padBoth("Kotlin", 11, '*'))
}
