#### Answer

Changing the greater than sign to a less than sign would change the
task of the entire algorithm. It would output the smallest element instead
of the largest one.
Making sure that we have the right relational operation in place is crucial
for achieving the desired result. Changing the operator in a conditional
primitive could change the whole "job" of the algorithm. Changing it in an
iterative one could lead to a different number of iterations, no iterations at
all, or infinite iterations.
