function [minsum, maxsum]=MyFunction(L)
sum=0;
for i=1:length (L)
sum=sum+L(i);
end
min=L(1);
max=L(1);
for i=1:length (L)
if L(i)<min
min=L(i);
end
if L(i)>max
max=L(i);
end
end
minsum=sum-max
maxsum=sum-min

Since you aren't allowed to use efficient tools (e.g. sort), you are forced to write slow code. I would not try to use eval to cheat here, although I doubt the grader will detect that, especially if you encapsulate it in str2func.
BUT: you are in luck. You were given the task to get the numbers without repitition. The unique function will automatically sort the output for you.

Since this question is supposed to be run in Octave, the students are forced to use other functions, since mink and maxk were introduced in R2017b, but aren't implemented in Octave.
