Next, S lines have 3 integers, Q, P, and D, where Q is the stock of pens available at the shop, P is the price per pen and D is the delivery fee.↵

_Output Format:_↵
A single line of output has an integer, which is the minimum amount Bob has to spend to purchase N pens.↵

Constraints:↵
1)- 1 <= N <=10000 ↵
11)- 1 <= S <= 100↵
lI1)- 0 <= 0 <= 10000↵
IV- 0 <= P<= 10000↵
V)- O<= D <= 1000000↵
