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…

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. package main package main import ( "strings" "golang.org/x/tour/wc" ) func WordCount(s string) map[string]int { //using make to initialise an empty map stringSlice := make(map[string]int) //words is a slice of substrings of s words := strings.Fields(s) for _, v := range words { //If key is not in the map, //then elem is the zero value for the map's element type. //zero value of int is 0 //incrementing it by 1 for the number of times the key is found stringSlice[v]++ } return stringSlice }

I’m starting to learn GoLang today and they’ve a coding playground on the homepage which is really cool and easy to get started but I’d still like to install it on my machine for developing complex apps and I think you too are looking for the same :P I’m on…
