|

|
|
|
||
|
|
### 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$
|
||
|
|
```
