How to create a slice with repeated elements

Question

I need a (non-loopy) way to create a slice of ints with n repeated copies of an element (say 10). Something equivalent of strings.Repeat("a", n) but for []int.

Answer 1

You could just capture it in a simple function:

func repeatedSlice(value, n int) []int {
    arr := make([]int, n)
    for i := 0; i < n; i++ {
        arr[i] = value
    }
    return arr
}

Here is a working example.
