Go错误：int类型的值作为int值

func Suma(vector []int) int {
    n := len(vector)
    if n == 0 {
        return 0
    } else {
        return Suma(vector[n] + vector[n-1])
    }
}

func main() {
    fmt.Println("Hello, 世界")
    vector := []int{1, 2, 3, 4, 5}
    res := Suma(vector)
    fmt.Println(res)
}

<code>
cannot use vector[n] + vector[n - 1] (value of type int) as []int value in argument to Suma
</code>

package main

import "fmt"

func Suma(vector []int) int {
    n := len(vector)
    if n == 0 {
        return 0
    } else {
        // You should call Suma recursively with a slice of the vector, excluding the last element.
        // Also, you need to add the current element (vector[n-1]) to the sum.
        return vector[n-1] + Suma(vector[:n-1])
    }
}

func main() {
    fmt.Println("Hello, 世界")
    vector := []int{1, 2, 3, 4, 5}
    res := Suma(vector)
