Question

As I was on a hike the other day I came across a small child in the woods. He told me his life story, with special mention of his disabled sister who loves flowers, and asked me for a favor.

He wanted a way to organize the flowers that he picks for her each day and perform a few basic tasks with them, along with a few restrictions. It is our goal to help him out!

He can only carry 25 flowers as adding any more causes many of them to become crushed.

All flowers should be able to be displayed

He should be able to add and remove flowers by using their name.

He needs to be able to search for a specific type of flower in his pack in case his sister has a special request.

He needs to be able to sort flowers by their names alphabetically in ascending order (A-Z)

He needs to show how many of each flower he has in his pack.

Now, I have started a simple program which will serve as guidance for you, please help me finish it. (Please don’t modify the code that I give you, just add your code where required)
