Quote:Write program that ...
This means that it is your duty to do the homework.
You are learning and homework is training, nobody can do it for you.
Do you think Usain Bolt asked someone to train for him when he was a beginner ?
You show no attempt to solve the problem yourself, you have no question, your main effort is pasting the requirement, you just want us to do your HomeWork.
HomeWork problems are simplified versions of the kind of problems you will have to solve in real life, their purpose
is learning and practicing
Take a sheet of paper and a pencil. Use your brain and solve the problem by hand. Since Harry Potter didn't gave you the solution, there is no magic, and the solution didn't jump to your face.
You solved the problem by following a procedure, that procedure is your algorithm. You need to write down the steps in a mechanical manner (computer like). The program will follow those steps.
We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
Any failure of you will help you to learn what works and what don't, it is called 'trial and error' learning.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.
