Given this code block
map[string]int {"hello":10, "foo":20, "bar":20}
I would like to print out
foo, 20
bar, 20
hello, 10
In the order of highest to lowest
Thanks!

You can implement the sort interface by writing the len/less/swap functions
func rankByWordCount(wordFrequencies map[string]int) PairList{
pl := make(PairList, len(wordFrequencies))
i := 0
for k, v := range wordFrequencies {
pl[i] = Pair{k, v}
i++
}
sort.Sort(sort.Reverse(pl))
return pl
}
type Pair struct {
Key string
Value int
}
type PairList []Pair
func (p PairList) Len() int { return len(p) }
func (p PairList) Less(i, j int) bool { return p[i].Value < p[j].Value }
func (p PairList) Swap(i, j int){ p[i], p[j] = p[j], p[i] }
