Cakes

This summer, you plan to organize a large party and invite many friends. They have a sweet tooth, so you plan to bake nice cakes for them. You know the recipe for a nice chocolate cake, and you want to cook as many of them as possible.

Given the $N$ ingredients needed to make a single cake and the ingredients that you have in your kitchen, how many cakes can you make?

• The first line of the input contains a single integer $N$.
• Then, $N$ lines follow, one for each ingredient. Each of these lines contains two positive integers: the first one is the required quantity of this ingredient per cake, the second one is the quantity of this ingredient you have in your kitchen.

The output should contain a single integer: the maximum number of cakes you can make using the available ingredients.

• $1 \leq N \leq 10$
• All ingredient quantities will be integers between $1$ and $10\\,000$.
