As a magician-to-be, Elyse needs to practice some basics. She has a stack of cards that she wants to manipulate.

To make things a bit easier she only uses the cards 1 to 10.

1. Retrieve a card from a stack

Return the card at position index from the given stack.

GetItem([]uint8{1, 2, 4, 1}, 2)
// Output: 4

2. Exchange a card in the stack

Exchange the card at position index with the new card provided and return the adjusted stack. Note that this will also change the input slice which is ok.

index := 2
new_card := 6
SetItem([]uint8{1, 2, 4, 1}, index, new_card)
// Output: []uint8{1, 2, 6, 1}

3. Create a stack of cards

Create a stack of given length and fill it with cards of the given value.

PrefilledSlice(8, 3)
// Output: []int{8, 8, 8}

4. Remove a card from the stack

Remove the card at position index from the stack and return the stack.

RemoveItem([]int{3, 2, 6, 4, 8}, 2)
// Output: []int{3, 2, 4, 8}
