Got Enough Money?

Create a function that returns any of the items you can afford in the store with the money you have in your wallet. Sort the list in alphabetical order.

Examples

items_purchase({
  "Water": "$1",
  "Bread": "$3",
  "TV": "$1,000",
  "Fertilizer": "$20"
}, "$300") ➞ ["Bread", "Fertilizer", "Water"]

items_purchase({
  "Apple": "$4",
  "Honey": "$3",
  "Fan": "$14",
  "Bananas": "$4",
  "Pan": "$100",
  "Spoon": "$2"
  }, "$100") ➞ ["Apple", "Bananas", "Fan", "Honey", "Pan", "Spoon"]

items_purchase({
  "Phone": "$999",
  "Speakers": "$300",
  "Laptop": "$5,000",
  "PC": "$1200"},
"$1") ➞ "Nothing"

Notes

Return "Nothing" if you can't afford anything from the store.
