### Wcipeg 2018 ECOO Qualifier

## Billows™

For a living, Bincent runs a company which produces snacks. One of his most popular products are Billows™, for which he constantly receives custom orders.

Usually, the accountants he employs around the country are responsible for processing custom orders. However, the Accountants' Committee for Safe Labour (ACSL) has initiated a country-wide strike. As a result, Bincent must personally review the orders placed to each factory, and calculate the amount of material that each factory requires to complete all orders.

Conveniently, each size is defined by the amount of material required. Can you help Bincent find the amount of material required at each factory?

Line 1: `F`, the number of factories
Each case consists of 3 lines:
An integer `N`, the number of different sizes produced at the factory

The integers

`b`

_{1},

`b`

_{2}, …

`b`, each representing the number of orders for size

_{n}`a`. All integers provided as input will be between 0 and 10000, inclusive.

_{i}### Output Format:

The output should have `F` integers on separate lines, each integer representing the amount of material which must be transported to each factory.

### Sample Input:

2 3 1 2 5 5 2 0 5 1 10 100 1000 10000 1 3 7 1 9
