Oh, now I totaly misunderstood the task! Thanks!

Where are you getting array length from? It's 2, because 2 is the 3rd index of input array (2nd argument).

But how do we actually get 2 in this situation? The array length is counting as 4, not 3.

actual and expected aren't reversed, your code filters strings with numbers in it, and the control function isn't doing that.

Sorry, misunderstood. thanks for the explanation

It's correct. 2 ^ 3 = 8.

Java's basic test is incorrect

    assertEquals(8, Kata.nthPower(new int[] {3,1,2,2}, 3));

Not well explained Kata, as a programmer I was expecting to solve a logic, not a mathematical problem

yes, i did use len()

Worked fine on my end. Are you filtering by len()?

In python, plenty of tests are failing because the expected and actual are reversed. Hence I couldn't submit my solution

Sample:
['RQWk', 'htGD', 'epmV', 'lIzS', 'cDYv', 'zWVg'] should equal ['0BLO', 'RQWk', 'Ee3S', 'htGD', 'epmV', 'lIzS', 'p9kz', 'cDYv', 'zWVg']
['DBAa', 'NVoa', 'nXfZ'] should equal ['O9wR', 'DBAa', 'NVoa', 'Wh6n', 'Ju8G', 'nXfZ', '1PXt']
