Q1: Pseudocode question

Each week’s sales  are to be discounted by 20% (due to taxes), resulting in that week’s net revenue. If the net revenue is more than $3000, the print out should state that. The revenue is what is to be printed. The last step should print out the total new revenue for that month.

Write the PseudoCode

Note: your pseudo code should include the basic programming logic structures:  Sequence, Decision, Looping

Hint: include the following as components of your pseudocode.

Initialization:  accumulator(s)?, counters? variables?

read  module?

calculate ?

Print ?  (A decision here)?

End?

Q2: Binary Search

Given a sorted array ( 1-based)

Array( 3, 15, 17, 18, 34, 89, 109, 256, 4096, 5000,5001, 6600, 6634, 7890)

and a target value of 15, show the sequence of  steps in the following table:

Tell me how many steps to find the target value and fill in the table…

Step     lowerbound    upper bound     midindex    value at mid index

1                  1                    14                   ?

Q3: Parsing Questions

Place parentheses correctly around these expressions

assume A, B, C are numeric while X, Y, Z are Boolean

1. A^2^3 / B / C
2. A > B and  B > C * 10
3. A – B – C * A
4. X and Not B or Z

Q4: Function Fun

Given the function below: where Double  means that parameters a, b are floating point numerics.

def fun( a: Double, b: Double ) =  b * a > a

Write out the result and return the answer

1. fun(4, 3)
2. fun(4, 0.5 )
3. fun(2 + 1, 2)
