You are standing at a magical well. It has two positive integers written on it: a and b. Each time you cast a magic marble into the well, it gives you a * b dollars and then both a and b increase by 1. You have n magic marbles. How much money will you make?

Example

For a = 1, b = 2, and n = 2, the output should be
magicalWell(a, b, n) = 8.

You will cast your first marble and get $2, after which the numbers will become 2 and 3. When you cast your second marble, the well will give you $6. Overall, you'll make $8. So, the output is 8.

You have two integer arrays, a and b, and an integer target value v. Determine whether there is a pair of numbers, where one number is taken from a and the other from b, that can be added together to get a sum of v. Return true if such a pair exists, otherwise return false.

Example

For a = [1, 2, 3], b = [10, 20, 30, 40], and v = 42, the output should be

A boy is walking a long way from school to his home. To make the walk more fun he decides to add up all the numbers of the houses that he passes by during his walk. Unfortunately, not all of the houses have numbers written on them, and on top of that the boy is regularly taking turns to change streets, so the numbers don't appear to him in any particular order.

At some point during the walk the boy encounters a house with number 0 written on it, which surprises him so much that he stops adding numbers to his total right after seeing that house.

For the given sequence of houses determine the sum that the boy will get. It is guaranteed that there will always be at least one 0 house on the path.

Example

For inputArray = [5, 1, 2, 3, 0, 1, 5, 0, 2], the output should be

An email address such as "John.Smith@example.com" is made up of a local part ("John.Smith"), an "@" symbol, then a domain part ("example.com").

The domain name part of an email address may only consist of letters, digits, hyphens and dots. The local part, however, also allows a lot of different special characters. Here you can look at several examples of correct and incorrect email addresses.

Given a valid email address, find its domain part.

Example

For address = "prettyandsimple@example.com", the output should be
