Example of a golang string slice and element removal by index (https://play.golang.org/p/Kw20T6apfLP)

slice_example.go

package main

import (
	"fmt"
	"sort"
)

func remove(slice []string, s int) []string {
	return append(slice[:s], slice[s+1:]...)
}

func index(data []string, term string) (int, bool) {
	idx := sort.Search(len(data), func(i int) bool {
		return string(data[i]) >= term
	})
	if idx < len(data) && data[idx] == term {
		return idx, true
	} else {
		return 0, false
	}
}

func main() {
	a := []string{"Hello", "golang", "world"}
	fmt.Printf("%v\n", a)
	fmt.Println(a[1])
	b := remove(a, 2)
	fmt.Printf("%v\n", b)

	idx, ok := index(a, "golang")
	if ok {
		fmt.Println(a[idx])
	} else {
		fmt.Println("oops, there's nothing there.")
	}
}
