| Hi there,
For some reason when I try to use unordered_str_cmp in my problems, it
pops up a pink screen stating that I have an uninitialized value in
str_cmp. However, my code works fine when I use just str_cmp. I have
attached the code, if someone could help me, I would be forever
thankful!

$PAR
Please refer to graph for problem #3 in Stewart 4th Edition, page 230.
$PAR
For each of the numbers a,b,c,d,e,r,s, and t, state whether the function
whose graph is shown has an absolute maximum or minimum, a local maximum
or minimum, or neither a maximum or minimum.
$PAR
The following abbreviations will be used in this problem:
$PAR
MAX = absolute maximum, $BR
MIN = absolute minimum, $BR
LMAX = local maximum, $BR
LMIN = local mimimum, $BR
NONE = no maximum or minimum. $PAR
$SOL $PAR
Enter the points where the following condition holds true: (e.g. MAX: a,b)
$PAR
MAX: {ans_rule(10)} $BR
MIN: {ans_rule(10)} $BR
LMAX: {ans_rule(10)} $BR
LMIN: {ans_rule(10)} $BR
NONE: {ans_rule(10)} $BR
EOT
$a = "b";
$b = "d";
$c = "b,e";
$d = "d,s";
$e = "a,c,r,t";
