Question

How to write a recursive function that calculates power in Kotlin

Answer 1

fun main() {
    println(power(2, 3)) // 8
    println(power(2, 4)) // 16
    println(power(3, 2)) // 9
    println(power(3, 3)) // 27
    println(power(5, 4)) // 625
}

fun power(x: Int, y: Int): Int {
    return if (y == 0) {
        1
    } else {
        x * power(x, y - 1)
    }
}



 
/*
run:
   
8
16
9
27
625
   
*/
