Tour of Go 2.0

Exercise: Slices

Implement Pic. It should return a [][]uint8 of size dy x dx. The program will render your values as a bluescale image.

You choose the math. Try (x+y)/2, x*y, or x^y and see what patterns emerge.

A few hints:

  • You’ll need a loop to allocate each inner []uint8.
  • Use uint8(intValue) to convert your computed values to the right type.
main.go ▶ Run in Playground 
package main

import "golang.org/x/tour/pic"

func Pic(dx, dy int) [][]uint8 {
}

func main() {
	pic.Show(Pic)
}
