# Basic drill L155 topic-15 micro-4 pattern-7
LESSON_UID = "basic-155"
spin_a, spin_b, spin_c = 824, 217, 238

src = [((k + 155) * spin_a + 4) % 241 for k in range(4 + 4 % 3)]
derived = [v * v if v % 2 == 0 else v + spin_b for v in src]
print("src", src)
print("derived", derived)
print("zip_sum", sum(x + y for x, y in zip(src, derived)))
