Exercise: Fibonacci closure

Let's have some fun with functions.
Implement a fibonacci function that returns a function (a closure) that returns successive fibonacci numbers.

/*
Exercise: Maps

Implement WordCount. It should return a map of the counts of each “word” in the string s. The wc.Test function runs a test suite against the provided function and prints success or failure.

You might find strings.Fields helpful.

/*
Exercise: Slices

Implement Pic. It should return a slice of length dy, each element of which is a slice of dx 8-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 include x^y, (x+y)/2, and x*y.

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

(Use uint8(intValue) to convert between types.)

/*
Exercise: Loops and Functions

As a simple way to play with functions and loops, implement the square root function using Newton's method.

In this case, Newton's method is to approximate Sqrt(x) by picking a starting point z and then repeating:

z= z- ( (z^2 -x) / (2*z) )

To begin with, just repeat that calculation 10 times and see how close you get to the answer for various values (1, 2, 3, ...).
