A tour of Go exercise: slices

ImplementPic. It shoshould return a slice of Lengthdy, Each element of which is a slicedx8-bit unsigned integers. When you run the program, it will display your picture, interpreting the integers as grayscale (well, bluescale) values.

The choice of image is up to you. Interesting functions includex^y,(x+y)/2, Andx*y.

(You need to use a loop to allocate each[]uint8Inside[][]uint8.)

(Useuint8(intValue)To convert between types.

 

package mainimport "code.google.com/p/go-tour/pic"func Pic(dx, dy int) [][]uint8 {    s := make([][]uint8,dx)    for i := range s {        s[i] = make([]uint8,dy)        for j := range s[i]{            s[i][j] = uint8(i * j)        }    }    return s}func main() {    pic.Show(Pic)}
