Removing elements from the middle of a slice
This is an example Go program illustrating removing an element from the middle of a slice.
package main import ( "fmt" ) func main() { strings := []string{"one", "two", "three", "four"} for i := range strings { // Copy strings into c so that strings doesn't get altered by // append. c := make([]string, len(strings)) copy(c, strings) // [0:i] includes elements from c[0] up to c[i-1]. If i=0, it // is empty. c[i+1:] includes the elements from c[i+1] to // c[len(c)-1]. If i+1=len(c)-1, it is empty. The final "..." // is necessary for appending a slice to a slice. sub := append(c[0:i], c[i+1:]...) for j := range sub { fmt.Printf("%s ", sub[j]) } fmt.Printf("\n") } }
The output of the example looks like this:
two three four one three four one two four one two three
