# Fair Distribution

Mr. Forhad has X children. One day, on his way home, he bought Y chocolates for his children. He doesn’t know if he can divide these Y chocolates equally among his X children. If he can’t, then he must buy some more chocolates so that he can divide the chocolates equally among his children.

Now, you need to write a program to help Mr. Forhad determine the minimum number of additional chocolates that he needs to by so that he can make the distribution fair.

## Input

Each line will have two integers **X** and **Y** (0 < X, Y < 150) where X is the number of children that Mr. Forhad has and Y is the number of chocolates that Mr. Forhad has already bought.

## Output

You must print one integer which is the minimum number of additional chocolates that Mr. Forhad needs to buy.
