I understand what you're trying to do, but I'm sure that the variable 'lim'
in your program is incorrect.
I've tried your program and the values of 'lim' do not look correct. For the
example with the five values given above, the value of lim becomes (at the
end of each iteration of the 'i' loop):
Are you sure this is correct? I expect you wanted the sequence to be 11, 10,
3, 2, 1. So you should try to figure out, why the program gets the wrong
value of the variable 'lim'.
Here is something more to think about: How is the variable 'MAX[i]' related
to the variable 'lim'? Should they always be the same?
