// A basket of fruits in the form of a hash map needs to be defined. The key
// represents the name of the fruit and the value represents how many of that
// particular fruit is in the basket. You have to put at least 3 different
// types of fruits (e.g. apple, banana, mango) in the basket and the total count
// of all the fruits should be at least 5.

// let mut basket =
// Two bananas are already given for you :)
basket.insert(String::from("banana"), 2);
// TODO: Put more fruits in your basket.
