#126 Practice Recursion Problem

What are the two parameters of the enigma method?

• x and y

• a and b

• a and z

• x and z

What is the base case?

• When a is greater than z

• When a is less than z

• When a equals z

• When a plus z equal 0

What is returned in the first recursive case when a > z?

• a + z

• a + Enigma(a-2, z)

• z + Enigma(a, z-1)

• a - z

 In the case where a < z, what does the method return?

• z + Enigma(a, z-1)

• a + Enigma(a-2, z)

•  a + z

•  z - Enigma(a, z-1)

What are the initial values passed to enigma in the example?

• 6 and 3

• 8 and 3

• 3 and 8

• 4 and 3

What is the next recursive call made after enigma(8, 3)?

• Enigma(6, 3)

• Enigma(5, 3)

• Enigma(8, 1)

• Enigma(10, 3)

At what point is the base case reached in the example?

• When Enigma(8, 3) is called

• When Enigma(4, 3) is called

• When Enigma(2, 3) is called

• When Enigma(2, 2) is called

What value will be returned by the base case enigma(2, 2)?

• 2

• 3

• 4

• 5

What is the final value returned by enigma(4, 3)?

• 7

• 9

• 11

• 13

What is the final result returned by the initial call enigma(8, 3)?

• 17

• 21

• 23

• 25
