Assignment 1 Bonus #3

I don’t know how to run test cases for Assignment 1 Bonus #3.
I tried to copy Leetcode example but it doesn’t work.

Is this test case correct?
testx = {
‘input’: {
‘num’: [5, 6, 9, 0, 2, 3, 4]
},
‘output’: 2,
}

then I ran this:
evaluate_test_case(find_element, testx)

this is the error:
TypeError: find_element() got an unexpected keyword argument ‘num’
