Remove same elements from two arrays Golang

php editor Apple brings you an article about deleting identical elements from two arrays. In programming, we often encounter situations where we need to delete the same elements in an array. This operation can help us process data better. This article will introduce how to use Golang language to delete the same elements from two arrays. I hope it will be helpful to your programming work. Let’s take a look!

Question content

a:=[]rune("/storage/emulated/0/Custom_Scripts/Golang/")

b:=[]rune("/storage/emulated/0/")

There are two slices a && b, in the loop we should take each element from the second slice $b and compare it with the elements in the first slice $a, if they are the same, then we Will start from the first slice $a The solution should be without any package except fmt (only for printing the final array) and by two ways: Use looping fists Second map

Trying to release it this way but I'm getting an out of range panic, can anyone help me?

package main
import(
"fmt"
)
func main() {
    fileMeta := 
[]rune("/storage/emulated/0/Custom_Scripts/Golang/")
    delChr := []rune("/storage/emulated/0")
    for i, j := range fileMeta {
        for _, m := range delChr {
            if m == j {
               //fileMeta[i] = ""
               fileMeta = append(fileMeta[:i], 
fileMeta[i+1:]...)
            }
        }
    }
    fmt.Println(fileMeta)
  }

Solution

I won’t reinvent the wheel:

package main

import (
    "fmt"
    "strings"
)

func main() {
    fileMeta := []rune("/storage/emulated/0/Custom_Scripts/Golang/")
    delChr := []rune("/storage/emulated/0")

    fm := string(fileMeta)
    pfx := string(delChr)

    if tail := strings.TrimPrefix(fm, pfx); len(tail) != len(fm) {
        fileMeta = []rune(tail)
    }

    fmt.Println(fileMeta, string(fileMeta))
}

BTW, do you really need to do this on []runes? This is unnatural for most applications - why not just use the correct string right away?
