Consider the following function:

def list_mystery2(a):
    for i in range(1, len(a) - 1):
        a[i] = a[i - 1] - a[i] + a[i + 1]

Indicate in the right-hand column what values would be stored in the list after the function list_mystery2 executes if each integer list below is passed as a parameter to it.

`a1 = [42, 42] list_mystery2(a1)`
`a2 = [6, 2, 4] list_mystery2(a2)`
`a3 = [7, 7, 3, 8, 2] list_mystery2(a3)`
`a4 = [4, 2, 3, 1, 2, 5] list_mystery2(a4)`
`a5 = [6, 0, -1, 3, 5, 0, -3] list_mystery2(a5)`
