the
"Expected: equal to -652
Actual: 978"
is an error that the test is giving me, its not calculated by me...
my output is 978 while the random tests tell me that the output should be -652

C++ kata is having major issues:

Expected: equal to -652
Actual: 978

i do not think that it should be even possible to get negative lengths from intervals
