+// 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 three different
+// types of fruits (e.g apple, banana, mango) in the basket and the total count
+// of all the fruits should be at least five.
+//
+// Make me compile and pass the tests!

+// hint.
