Given an array of numbers, return the sum of all the numbers.

--hints--

sum_array([1, 2, 3, 4, 5]) should return 15.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(sum_array([1, 2, 3, 4, 5]), 15)`)
}})

sum_array([42]) should return 42.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(sum_array([42]), 42)`)
}})

sum_array([5, -2, 7, -3]) should return 7.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(sum_array([5, -2, 7, -3]), 7)`)
}})

sum_array([203, 145, -129, 6293, 523, -919, 845, 2434]) should return 9395.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(sum_array([203, 145, -129, 6293, 523, -919, 845, 2434]), 9395)`)
}})

sum_array([0, 0]) should return 0.

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(sum_array([0, 0]), 0)`)
}})
