map 辅助函数
- 有序遍历
map（根据map中KEY进行排序，依次遍历）
var tm = make(map[string]string)
tm["b"] = "c"
tm["a"] = "b"
tm["1"] = "2"
tm["c"] = "d"
WalkStringStringMapDeterministic(tm, func(k string, v string) bool {
fmt.Println("key:", k, "value:", v)
return true
})Output:
key: 1 value: 2
key: a value: b
key: b value: c
key: c value: d
