Grayscale

Report a typo

Let's create the simplest function that converts a 24-bit color to 8-bit grayscale.

Write the code for the function

colorValueToGrayscale(red: Int, green: Int, blue: Int): Int

which takes as parameters a pixel's 3 color values (red, green, and blue) and returns a grayscale value, which is the mean value of the input parameters (use integer operations).

Sample Input 1: 

0 100 200

Sample Output 1: 

100
Write a program in Kotlin
fun main() {
val (x1, x2, x3) = readLine()!!.split(" ")
val red = x1.toInt()
val green = x2.toInt()
val blue = x3.toInt()

println(colorValueToGrayscale(red, green, blue))

}

fun colorValueToGrayscale(red: Int, green: Int, blue: Int): Int {
// Write your code here

//
}
