Even the Last
You are given list of integers (int). You should find the sum of the elements with even indexes (0th, 2nd, 4th...). Then multiply this summed number and the final element of the list together. Don't forget that the first element has an index of 0.
For an empty list, the result will always be 0 (zero).
Input: List of integers (int).
Output: An integer (int).
Examples:
assert checkio([0, 1, 2, 3, 4, 5]) == 30 assert checkio([1, 3, 5]) == 30 assert checkio([6]) == 36 assert checkio([]) == 0
How it is used: Indexes and slices are important elements of coding. This will come in handy down the road!
Preconditions:
0 ≤ len(array) ≤ 20
all(isinstance(x, int) for x in array)
all(-100 < x < 100 for x in array)
