Sold out!

#042Mini challengeMapsSlices6 min

The bakery's stock map has how many of each are left, and sold lists the sales in order (one at a time; there's always one to sell). Write SellOut(stock, sold): when something reaches 0, delete it from stock and add its name to a slice, in the order things sold out. Nothing sold out gives an empty slice.

Examples

SellOut(map[string]int{"bun": 2, "pie": 1}, []string{"pie", "bun"})→['pie']

SellOut(map[string]int{"bun": 1, "tart": 1}, []string{"tart", "bun"})→['tart', 'bun']

The functionfunc SellOut(stock map[string]int, sold []string) []string

main.go

package main

func SellOut(stock map[string]int, sold []string) []string {
	out := []string{}
	for _, item := range sold {
		stock[item]--
		// your code here: if it reached 0, delete it and add its name to out
	}
	return out
}
