Report Card V6 - Class Statistics in Kotlin

Practice

Compute three class statistics from a list of scores: the highest, the lowest, and the average.

You start with:

val scores = listOf(92, 78, 85, 67, 74, 88, 91, 58)

Build:

Highest: 92
Lowest: 58
Average: 79

Rules:

  • highest is the largest value in scores.
  • lowest is the smallest value in scores.
  • average is the sum of all scores divided by how many there are, rounded down (integer division).
  • Print "Highest: ", "Lowest: " and "Average: " on three lines, in the order of the sample output (println("Highest: $highest")).

Use scores.max() and scores.min() on the list; sum with a loop.

val scores = listOf(92, 78, 85, 67, 74, 88, 91, 58)

val highest = scores.max()
val lowest = scores.min()
var total = 0
for (s in scores) {
    total += s
}
val average = total / scores.size

println("Highest: $highest")
println("Lowest: $lowest")
println("Average: $average")
