Please help me implement bubble sort.It works fine if I call it with a hardcoded slice from the main() but if I call it with dynamic input from Scan it breaks

here is my code so far:

package main

import "fmt"

func main() {
    fmt.Println("Enter a maximum of 10 numbers: ")

    var inputs int
    fmt.Scanln(&inputs)
    inputSlice := make([]int, inputs)

    BubbleSort(inputSlice)

    fmt.Println(inputSlice)

}

func BubbleSort(input []int) {

    for i := 0; i < len(input)-1; i   {
        for j := 0; j < len(input)-i-1; j   {
            Swap(input, j)
        }
    }
}

func Swap(input []int, j int) {
    if input[j] > input[j 1] {
        input[j], input[j 1] = input[j 1], input[j]
    }
}

terminal:

coder:~/project$ go run bubblesort.go
Enter a maximum of 10 numbers:
12 24 54 65 11
coder:~/project$ 4 54 65 11
bash: 4: command not found

Do a little debugging by adding print lines in between your codes and see what's actually happening, you were just reading input the wrong way from command line

    fmt.Println(`Enter the number of integers`)
    var n int
    if m, err := Scan(&n); m != 1 {

    inputSlice := make([]int, n)
    ReadN(inputSlice, 0, n)

    //Your Input Printing Out
    fmt.Println(inputSlice)

    //Calling Function
    BubbleSort(inputSlice)

    //Output
    fmt.Println(inputSlice)

    for i := 0; i < len(input)-1; i   {

func Scan(a *int) (int, error) {
    return fmt.Scan(a)
