Part $4$: Flower Bunches

This is a more challenging problem that will require you to take your time and design a solution. We have a scenario where we have high value flowers, low value flowers, and greenery $($the decorative leaves and accessories. Given a budget, we want to spend our entire budget to create a bunch of flowers. Write a function make$\_$bunch$($high$,$ low, green, budget$)$ takes integer for number of high, low and greenery items, and a budget, and returns a list of the flowers used to make the bunch.

There are a number of rules

$$ High value flowers which cost $4$ each, and a maximum of $4$ can be used, regardless of how many flowers are available.

$$ Low value flowers cost $2$ each, and any number can be used

$$ Greenery costs $0\mathrm{.}50$ each, and a bunch needs a minimum of $4$ items of greenery, with no

maximum

$$ The entire budget must be used.

$$ If a bunch cannot be created within the rules and there is budget left over, then return an

empty list $([])$

$$ If a bunch cannot be created due a a lack of flowers, return an empty list $([])$

outputs:

make$\_$bunch$(4,8,10,15)->[3,0,6]$

Here, we input $4$ high values, $8$ low values, $10$ greenery, and a budget of $15.$ The resulting output is $3$ high value flowers $(12),0$ low values flowers, and $6$ greenery items $(3)$

make$\_$bunch$(3,8,10,19)->[3,2,6]$

Outputs $3$ large flowers $(12),2$ low value flowers $(4),$ and $6$ pieces of greenery $(3)$

make$\_$bunch$(4,8,2,15)->[]$

Here, there is not enough greenery to satisfy the minimum rules, and so an empty list is returned.
