Answer
1) [30, 1, 2, 1, 0, 1, 21, 13]
2) [1, 21, 13, 1, 21, 13]
3) [1, 21, 13, 1, 21, 13]
4) [1, 2]
5) 1
Work Step by Step
1) “+” operator add the whole of one list behind the other list. [30, 1, 2, 1, 0] + [1, 21, 13] = [30, 1, 2, 1, 0, 1, 21, 13]
2) 2 * [1, 21, 13] = [1, 21, 13] + [1, 21, 13] = [1, 21, 13, 1, 21, 13]
3) [1, 21, 13] * 2 = [1, 21, 13] + [1, 21, 13] = [1, 21, 13, 1, 21, 13]
4) Return slice, which contains second and third element : [1,2]
5) Return 4th element : 1
