How to remove elements from a slice in Go?

In Go language, to remove an element from a slice, you can achieve this by using slice slicing operation. Here is a common method:

func removeElement(slice []int, index int) []int {
    return append(slice[:index], slice[index+1:]...)
}

This function takes a slice and the index of the element to be removed as parameters, and returns a new slice after removing the specified element. It uses slicing operations on the slice to rejoin the parts before and after the element to be deleted, achieving the effect of removing the specified element.

Here is an example of how to use it:

slice := []int{1, 2, 3, 4, 5}
index := 2
slice = removeElement(slice, index)
fmt.Println(slice) // 输出 [1 2 4 5]

In this example, we removed the element at index 2 from the slice, resulting in the final output of [1 2 4 5].
