How do I delete a slice element

I'm in the process of learning Golang, and I'm currently trying to create a Todo project.

My knowledge is limited to the GO base.
Please take a look at my code and tell me how I can delete a task.

The user writes in the console:

add Eat add Sleep add Study

Then they write:

list

to check the tasks

For example, if they want to delete the second task (Sleep), and I write del 1, it will delete the first element of the slice, which is 0.

And every time I write del 2, it will still delete the first element.

And now I need to make it so that I can delete:

a) By the title

b) By the number of the task location

Thank you all!!!

I'm stuck at the "Creating a task deletion command" stage. package main

import ( "bufio" "fmt" "os" "strings" "time" ) type Todo struct { Heading string Text string Creationtime time.Time Completed bool LeadTime time.Time } func main() { todos := []Todo{} _ = todos scanner := bufio.NewScanner(os.Stdin) for { scanner.Scan() input := scanner.Text() words := strings.Split(input, " ") switch words[0] { case "add": todo := Todo{ Heading: words[1], Text: strings.Join(words[2:], " "), Creationtime: time.Now(), Completed: false, } todos = append(todos, todo) case "list": for _, todo := range todos { fmt.Println(todo.Heading, todo.Text) } case "del": var n int todos = append(todos[:n], todos[n+1:]...)
