For each of the five points labeled by comments, identify each of the assertions in the table below as either being always true, never true, or sometimes true / sometimes false.

def mystery5(a):
    b = 0
    c = 0

    # Point A
    while a != 0:
        # Point B
        c = a % 10

        if c % 2 == 0:
            b += 1
        else:
            b = 0
            # Point C

        a = a // 10
        # Point D

    # Point E
    return c

Fill in each box of the the table below with ALWAYS, NEVER or SOMETIMES.

a != 0 c % 2 == 0 b > 0
Point A
