Question

Transcribed Image Text:## Format Requirement
Algorithms in pseudo code **MUST** be placed in
code blocks/fences, and use
highlighter.
Algorithms should follow the pseudo code standard
described in *Pseudocode Handout*.
срр
as the syntax
Do NOT change the template except the answer
portion.
Formulas and equations should be in math mode
using Latex math symbols.
- Markdown math tutorial:

h.pdf
Two ways to enter math mode:
Insert a pair of dollar signs: \$your
equations go here\$. This is the inline math mode.
*Notice that there is no space between the \$ and
the letter*.
Insert a pair of double-dollar signs: \$\ $
your equations go here \$\$, which produces a
standalone equation/formula set.
![Consider the following algorithm:
срр
ALGORITHM Secret (A[0..n â^' 1])
7/Input: An array A[0..n â^' 1] of n real numbers
minval <- A[0]
maxval <- A[0]
for i <- 1 to n - 1 do
if A[i]< minval
minval <- A[i]
if A[i]> maxval
maxval <- A[i]
return maxval â^' minval
1. What does this algorithm compute?
2. What is its basic operation?
3. How many times is the basic operation executed?
4. What is the efficiency class of this algorithm?
5. Suggest an improvement, or a better algorithm
altogether, and indicate its efficiency class. If
you cannot do it, try to prove that.
