How to get all the possible Substrings of a String in Go - Step by Step Examples

How to get all the possible Substrings of a String in Go ?

Answer

To get all possible substrings of a string in Go, you can use nested loops to iterate through each combination of start and end indices.

✐ Examples

1 All Substrings of 'Hello'

In this example,

We create a variable named str with a value of 'Hello'.
We initialize an empty slice named substrings to store all substrings.
We use nested loops to iterate through each possible start and end index combination.
For each combination, we extract the substring using slicing and add it to the substrings slice.
Finally, we print the substrings slice.

Go Program

package main
import (
    "fmt"
)
func main() {
    str := "Hello"
    substrings := []string{}
    for i := 0; i < len(str); i++ {
        for j := i + 1; j <= len(str); j++ {
            substrings = append(substrings, str[i:j])
        }
    }
    fmt.Println("All substrings:", substrings)
}

Output

All substrings: [H He Hel Hell Hello e el ell ello l ll llo l lo o]
