Title: 39.Sorting.go
Author: OpenSource
Date: 2017-05-22
Description: For Study
Go’s sort package implements sorting for builtins and user-defined types.
We’ll look at sorting for builtins first.
package main
import (
func main(){
// Sort methods are specific to the builtin type; here’s an example for strings.
// Note that sorting is in-place, so it changes the given slice and doesn’t return a new one.
strs := []string{"c", "a", "b"}
fmt.Println("Strings =>", strs)
// An example of sorting ints.
ints := []int{7, 2, 4}
fmt.Println("Ints =>",ints)
// We can also use sort to check if a slice is already in sorted order.
s := sort.IntsAreSorted(ints)
fmt.Println("sort.IntsAreSorted(ints) => ", s)
// Running our program prints the sorted string and int slices and true
// as the result of our AreSorted test.
You can’t perform that action at this time.
