How to remove the last occurrence of a word from a string in Kotlin

Answer 1

fun removeLastOccurrenceOfAWordFromAString(str: String, word: String): String {
	// Find the position of the last occurrence of word in str
    val pos = str.lastIndexOf(word)

    return if (pos != -1) {
               	str.substring(0, pos) + str.substring(pos + word.length)
            } else {
                str
            }
}

fun main() {
    var str = "kotlin c python java c++ kotlin php rust"
    val word = "kotlin"

    str = removeLastOccurrenceOfAWordFromAString(str, word)

    println(str)
}
