You have a shopping cart with sweets – it should be presented as Map<String, Integer>, where the key is the name of a sweet and the value is its price. You should fill Map<String, Integer> from console and then count the total cost of the shopping cart.

Firstly, you get the number of sweets in the cart; then, you get their names and prices.

choco 10
cake 50

Write a program in Kotlin
fun countSum(sweets: Map<String, Int>): Int {
// write your code
}
