prev | next | chance

Return the sum of the numbers in the array, returning 0 for an empty array. Except the number 13 is very unlucky, so it does not count and numbers that come immediately after a 13 also do not count. sum13([1, 2, 2, 1]) → 6 sum13([1, 1]) → 2 sum13([1, 2, 2, 1, 13]) → 6 ...Save, Compile, Run |
