my question might confusing.
Please write a code for me ....

No, it's not the question that's "confusing." Rather, it's YOU who is confusing the Monastery's objectives with your desires.

The way PM works -- or, "is supposed to work" -- is by HELPING folks who have questions learn how to answer them. Yes, -- sigh -- sometimes we do write code rather than providing answers that help the original posters work out solutions, but the bottom line is in the observation that "If you give a man a fish, he eats for a day; if you teach him how to fish, he eats for the rest of his life."

So, please, apply your best efforts to the solutions intrinsic-to or hinted-at in some of the prior replies. And, remember, "there's more than one way to do it."
