Recap - Approved Totals

Part of the Logic & Flow section of Coddy's Kotlin journey. Lesson 35 of 63.

Challenge

Medium

Complete approvedTotal with parameters values: List<Int>, minimum: Int, factor: Int. Keep values at least minimum, multiply each by factor, then sum the transformed values. Return zero if nothing qualifies. Use a collection pipeline.

Unless stricter bounds are stated above, collections contain at most 100 elements at each level, and integer arguments and integer collection values are between -1000 and 1000. Text supplied for parsing can include invalid or out-of-range representations as described.

Return a value of type Int. Keep the supplied input/output code. It reads scalar arguments one per line; a list starts with its count followed by its elements, and a map starts with its entry count followed by each key and value. Nested lists repeat the count-and-elements format for each row. The supplied main prints the return value followed by one newline. Lists use Kotlin's standard bracketed format; print no additional labels.

Try it yourself

fun approvedTotal(values: List<Int>, minimum: Int, factor: Int): Int {
    // Write your solution here.
    return 0
}
fun main() {
    val valuesCount = readln().toInt()
    val values = mutableListOf<Int>()
    for (i0 in 0 until valuesCount) {
        val valuesItem = readln().toInt()
        values.add(valuesItem)
    }
    val minimum = readln().toInt()
    val factor = readln().toInt()
    println(approvedTotal(values, minimum, factor))
}
