What exactly do people mean by corner cases

what could be a possible corner cases for these constraints ??

1<=test<=100;

0<=array length<=50;

1<=size of k<=100000000; where k is an element of array

It depennds the one question. It usually means some case where normally people will not think might fall. Suppose in integer division people may not think division by 0, but it is a corner case.

Each variable having either upper bound values or lower bound values.

as you mentioned your constraints, one example could be

test=100: size=100: each element =100000000

another can be:

test=1 size=0
