A software company wants to estimate the likelihood of resolving a software bug within a certain number of hours. The time to resolve the bug can be represented by a uniform distribution between [A] and [B] hours.

In the blank spaces below, write the value(s) printed by each call to the following function. def mystery(z): x = 1 y = 1 while z > 2: y = y + x x = y – x z = z – 1 print(y) mystery(3) [l1] mystery(4) [l2] mystery(5) [l3] mystery(6) [l4]

In the blank spaces below, write the value(s) printed by each call to the following function. def mystery(n): x = 0 y = 0 while n > 0 && n % 2 == 0: x = x + 1 y = y * 10 + n % 10 n = n // 10 print(x, y) mystery(5) [l1] mystery(28) [l2] mystery(346) [l3] mystery(265408) [l4]

In the blank spaces below, write the value(s) printed by each call to the following function. def mystery(y): x = 0 z = 0 while y > 0: x = x + 1 z = z + y % 10 y = y // 10 print(x, z) mystery(8) [l1] mystery(32) [l2] mystery(184) [l3] mystery(8239) [l4]
