Index Power
You are given a list with positive integers (int) and an integer (int) N. You should find the N-th power of the element in the list with the index N. If N is outside of the list, then return -1. Don't forget that the first element has the index 0.
Let's look at a few examples:
- list = [1, 2, 3, 4] and N = 2, then the result is 32 == 9;
- list = [1, 2, 3] and N = 3, but N is outside of the list, so the result is -1.
Input: Two arguments.A list of integers (int) and an integer (int).
Output: The result as an integer (int).
Examples:
assert index_power([1, 2, 3, 4], 2) == 9 assert index_power([1, 3, 10, 100], 3) == 1000000 assert index_power([0, 1], 0) == 1 assert index_power([1, 2], 3) == -1
How it is used: This mission teaches you how to use basic arrays and indexes when combined with simple mathematics.
Precondition:
0 < len(array) ≤ 10
0 ≤ N
all(0 ≤ x ≤ 100 for x in array)
