CF441A Valera and Antique Items

Valera is a collector. Once he wanted to expand his collection with exactly one antique item. Valera knows $ n $ sellers of antiques, the $ i $ -th of them auctioned $ k_{i} $ items. Currently the auction price of the $ j $ -th object of the $ i $ -th seller is $ s_{ij} $ . Valera gets on well with each of the $ n $ sellers. He is perfectly sure that if he outbids the current price of one of the items in the auction (in other words, offers the seller the money that is strictly greater than the current price of the item at the auction), the seller of the object will immediately sign a contract with him. Unfortunately, Valera has only $ v $ units of money. Help him to determine which of the $ n $ sellers he can make a deal with.

In the first sample Valera can bargain with each of the sellers. He can outbid the following items: a $ 40000 $ item from the first seller, a $ 20000 $ item from the second seller, and a $ 10000 $ item from the third seller. In the second sample Valera can not make a deal with any of the sellers, as the prices of all items in the auction too big for him.
