`Intersperse` inserts a separator between each element of the slice. Returns an empty slice if the input is empty. Returns the original element if the input has only one element.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
u "github.com/rjNemo/underscore"
|
|
)
|
|
|
|
func main() {
|
|
nums := []int{1, 2, 3, 4, 5}
|
|
fmt.Println(u.Intersperse(nums, 0)) // [1, 0, 2, 0, 3, 0, 4, 0, 5]
|
|
|
|
// Useful for formatting
|
|
words := []string{"apple", "banana", "cherry"}
|
|
fmt.Println(u.Intersperse(words, ",")) // ["apple", ",", "banana", ",", "cherry"]
|
|
|
|
// Single element - no separator added
|
|
single := []int{42}
|
|
fmt.Println(u.Intersperse(single, 0)) // [42]
|
|
}
|
|
```
