In Go language slice is more powerful, flexible, convenient than an array, and is a lightweight data structure. The slice is a variable-length sequence which stores elements of a similar type, you are not allowed to store different type of elements in the same slice. Go language allows you to sort the elements of the slice according to its type. So, a string type slice is sorted by using the following functions. These functions are defined under the sort package so, you have to import sort package in your program for accessing these functions:
1. Strings: This function is used to only sorts a slice of strings and it sorts the elements of the slice in increasing order.
func Strings(scl string)
Here, slc represent a slice of strings. Let us discuss this concept with the help of an example:
Slices(Before): Slice 1: [abc rwp def por ber erj] Slice 2: [Rabbit Fish Dog Parrot Cat Hamster] Slices(After): Slice 1 : [abc ber def erj por rwp] Slice 2 : [Cat Dog Fish Hamster Parrot Rabbit]
2. StringsAreSorted: This function is used to check whether the given slice of strings is in sorted form(in increasing order) or not. This method returns true if the slice is in sorted form, or return false if the slice is not in the sorted form.
func StringsAreSorted(scl string) bool
Here, scl represents a slice of strings. Let us discuss this concept with the help of an example:
Slices: Slice 1: [abc ber def erj por rwp] Slice 2: [Rabbit Fish Dog Parrot Cat Hamster] Result: Is Slice 1 is sorted?: true Is Slice 2 is sorted?: false
