## 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.

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 a variation of sequential search that
scans a list to return the number of
**occurrences** of a given search key in the list.
Does its efficiency differ from the efficiency of
classic sequential search? Why?
#### Answer:

Expert Solution

Step 1

Second image question is solved below:

Sequential search:

Best Case: When the searched element is the first in the list, traditional sequential search will discover it in a single operation. i.e, Θ(1)

Worst Case: Worst case will happen when searched item is last item in list for which sequential algorithm will go through complete list taking Θ(n) time.
