Match each step of the engineering design process with the correct example of what an engineer does during each step.
define the problem
brainstorming solutions
research ideas/ explore possibilities
specify constraints and identify criteria
consider alternative solutions
select an approach
develop a written design proposal
make a model/ prototype
test and evaluate
refine/ improve
create/ make product
communicate results
a.
an engineer using a decision matrix to determine which one of his/her solution ideas meets the established criteria and constraints.
b.
an engineer creates a mind-map of potential solution ideas regardless of feasibility.
c.
an engineer uses data to make decisions about design alterations.
d.
an engineer does not allow preconceptions to limit the different ways in which a problem could be solved.
e.
an engineer develops a plan of action to produce a solution to a problem.
f.
an engineer creates a 3d visual representation of his/her proposed design solution.
g.
an engineer creates a formal presentation that summarizes his/her process for developing a solution to a problem.
h.
an engineer collects and analyzes data to determine how well his/her solution solves the problem.
i.
an engineer will document the essential guidelines and limitations for solving a problem.
j.
an engineer develops a short and descriptive statement that identifies what the problem is, who should address the problem, and when and how a problem should be adressed.
k.
an engineer sends his/her design to a maunfacturer for production.
l.
an engineer works to determine what mathematical and scientific knowledge is essential for creating a soltuion to a problem.

What is the worst-case complexity of the maxrepeats function? assume that the longest string in the names array is at most 25 characters wide (i.e., string comparison can be treated as o( class namecounter { private: int* counts; int nc; string* names; int nn; public: namecounter (int ncounts, int nnames); int maxrepeats() const; }; int namecounter: : maxrepeats () { int maxcount = 0; for (int i = 0; i < nc; ++i) { int count = 1; for (int j = i+1; j < nc; ++j) { if (names[i] == names[j]) ++count; } maxcount = max(count, maxcount); } return maxcount; }
