## shoppingsummarycounter |
||||
|
||||
### Instructions |
||||
|
||||
You have a receipt from the grocery store and you want to know how many of each item you bought. Write a function that returns this summary. |
||||
|
||||
Given a `string` count the total amount of times each item appears in it and return a summary including the item and its number of appearances as an `int`. |
||||
|
||||
### Expected function |
||||
|
||||
```go |
||||
func ShoppingSummaryCounter(str string) map[string]int { |
||||
|
||||
} |
||||
``` |
||||
|
||||
### Usage |
||||
|
||||
Here is a possible program to test your function: |
||||
|
||||
```go |
||||
package main |
||||
|
||||
import "fmt" |
||||
|
||||
func main() { |
||||
summary := "Burger Water Carrot Coffee Water Water Chips Carrot Carrot Burger Carrot Water" |
||||
for index,element := range ShoppingSummaryCounter(summary){ |
||||
fmt.Println(index,"=>",element) |
||||
} |
||||
} |
||||
``` |
||||
|
||||
And its output: |
||||
|
||||
```console |
||||
$ go run . | cat -e |
||||
Burger => 2$ |
||||
Water => 4$ |
||||
Carrot => 4$ |
||||
Coffee => 1$ |
||||
Chips => 1$ |
||||
``` |
