strings.SplitAfter()

The SplitAfter() function is an inbuilt function of strings package which is used to split the given string (slice) into all substrings after each instance of the given separator. It accepts two parameters – a slice (string) and a separator and returns a slice of those substrings.

Note:

• If the slice does not contain a separator and the separator is not empty, the SplitAfter() function returns a slice of length 1 whose only element is the given string.
• If separator is empty, SplitAfter() function splits after each UTF-8 sequence. If both the string and separator are empty, SplitAfter() function returns an empty slice.

Syntax:

func SplitAfter(str, sep string) []string

Parameter(s):

• str : The string (slice) whose value is to be separated.
• sep : Separator.

Return Value:

The return type of SplitAfter() function is a []string, it returns a slice of those substrings.

Example 1:

// Golang program to demonstrate the
// example of strings.SplitAfter() Function

package main

import (
	"fmt"
	"strings"
)

func main() {
	fmt.Printf("%q\n", strings.SplitAfter("The sun is very bright", " "))
	fmt.Printf("%q\n", strings.SplitAfter("a man a plan a canal panama", "a "))
	fmt.Printf("%q\n", strings.SplitAfter("The sun is very bright", ""))
	fmt.Printf("%q\n", strings.SplitAfter("", ","))
}

Output:

["The " "sun " "is " "very " "bright"]
["a " "man a " "plan a " "canal panama"]
["T" "h" "e" " " "s" "u" "n" " " "i" "s" " " "v" "e" "r" "y" " " "b" "r" "i" "g" "h" "t"]
[""]

Example 2:

// Golang program to demonstrate the
// example of strings.SplitAfter() Function

package main

import (
	"fmt"
	"strings"
)

func main() {
	fmt.Printf("%q\n", strings.SplitAfter("The#sun#is#very#bright", "#"))
	fmt.Printf("%q\n", strings.SplitAfter("The, sun, is, very, bright", ", "))
	fmt.Printf("%q\n", strings.SplitAfter("Delhi Mumai Indore Gwalior", " "))
}

Output:

["The#" "sun#" "is#" "very#" "bright"]
["The, " "sun, " "is, " "very, " "bright"]
["Delhi " "Mumai " "Indore " "Gwalior"]
