Tenpin bowling scores can range from 0 (all gutter balls) to 300 (a perfect game). If you are unfamiliar with scorekeeping, please see the Resources tab for a quick description.

A complete record of a 10 frame bowling game can be given as a list of the number of pins knocked down by each ball in sequence from the beginning to the end of the game.

Create a function whose argument is such a list. The function should return the final score.

Examples

bowling([10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10]) ➞ 300

bowling([4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4]) ➞ 80
