Benji loves his money very much; however, he is also obsessed with wasting money when he sees discounts. What a tragedy!
Benji wants you to help him determine if an item is worth it to purchase.
He found ~N~ items in a store, with the ~i~-th item having an original price of ~c_i~ and a discount of ~d_i~ in percent off. He will also tell you ~T~, his threshold.
The first line of the input will contain two integers ~N~ ~(1 \le N \le 10^6)~ representing the number of items, and ~T~ ~(0 \le T \le 10^9)~, his threshold.
The next ~N~ lines will contain two integers ~c_i~ ~(1 \le c_i \le 10^9)~ and ~d_i~ ~(0 \le d_i \le 100)~ where ~(0 \le i \le N)~.
Output an integer ~K~ the number of items Benji can purchase whose price is less than or equal to his threshold.
5 7 100 90 100 93 100 95 10 10 10 40
Benji can buy the second, third, and last item. After discount, the first item cost ~10~, the second item cost ~7~, the third item cost ~5~, the forth item cost ~9~, and the fifth item cost ~6~.
