                                F = 1

                                set result = F(K)

                                write result

end program

Function F(N) as integer

         if N == 1 Then

                                           set F = 1

         else

                                           set F = N * F(N-1)

                                                                   set N = N-1

                     end if

Answer:

6, 1, 4, 3

• What occurs during max = x in this pseudocode

Def find_max (L);

        Max = 0

        For x in L;

               If x > max;

                Max = x

Return max

• Max is declared as a variable
• Max is compared to another variable
• Max is set equal to the largest number
• Max is set equal to an ongoing array

• What is displayed at step 5 in the pseudocode if the value of num1 =3 and num2 = 2?

• Step1 : Start
• Step2 : Declare num1, num2, sum as integers
• Step3 : Read values num1 and num2
• Step4 : sum = num1 + num2
• Step5 : Display sum – 1
• Step6 : Stop

                          Answer: 2, 3, 4, 5
