Donna likes to shop online. The main reason is that she gets a lot of offer! There are M online shops from where she purchases her items. The prices of the same item vary in both the shops. She needs to buy N items in all. And each she can buy each item in any one of the shops. All the shops offer certain offer. If she buys the item in one shop, she gets a offer coupon for the i+1th item in the same shop. But if she purchases the i+1th item from a different shop, she cannot use the offer coupon. For example, if she buys the h item in Shop j and gets a offer of X pounds. Let the price of i+1th item be Y pounds in shop j and Z pounds in shop k. If she purchases the i+1th item from shop j she can use the offer coupon and hence, will have to pay Y- X pounds. If she purchases the i+1th item from shop k she cannot use the offer coupon and hence, will have to pay Z pounds. Note: If the offer given is more than price of the item in the shop, i.e. if Y-X< 0, the item is given free but she does NOT get any money back. Donna wants to spend as less as possible and wants your help. She starts buying from item 1 and goes on till item N in that order. Your task is simple. Tell her the least amount to spend to get all the N items. Input: 1 24 1234 4321 2321 1211 Output: 2.
