What will be the output of the following algorithm?
STEP 1: Start
STEP 2: Let a = 1
STEP 3: Print a
STEP 4: Let b = 1
STEP 5: Print b
STEP 6: Let i = 5
STEP 7: Let the value of c = a + b
STEP 8: Let the value of i = i - 1
STEP 9: If the value of i = 0 then goto STEP 14
STEP 10: Print the value of c
STEP 11: Let the value of a = b
STEP 12: Let the value of b = c
STEP 13: Goto STEP 7
STEP 14: Stop

1 1 2 3 5 8

1 1 2 3 5

1 1 2 3 5 8 13
