Since indexing starts from zero, an element present at 3rd index is 7. So, the output is 7.
To find the output of A[3] where A = [1, 4, 6, 7, 9, 66, 4, 94], you’re essentially accessing the element at index 3 of the list A. In Python, indexing starts from 0, so the element at index 3 is the fourth element in the list.
