Find element in a slice and move it to first position?

Example

package main
 
import (
    "fmt"
)
 
func main() {
	sliceInt := []int{11,2, 19, 220, 31, 5, 65, 70, 100}
	find:=65
	fmt.Println(sliceInt)
    if len((sliceInt)) == 0 || (sliceInt)[0] == find {
        fmt.Println(sliceInt)
		return			
    } 
    if (sliceInt)[len(sliceInt)-1] == find {
        (sliceInt) = append([]int{find}, (sliceInt)[:len(sliceInt)-1]...)
        fmt.Println(sliceInt)
		return
    } 
    for p, x := range sliceInt {
        if x == find {
            (sliceInt) = append([]int{find}, append((sliceInt)[:p], (sliceInt)[p+1:]...)...)
            break
        }
    }
	fmt.Println(sliceInt)
}

Output

[11 2 19 220 31 5 65 70 100]
[65 11 2 19 220 31 5 70 100]
