Hi ikegami,

can you please explain why using the use sort 'stable'; pragma would be important? Admittedly, the sorting block is peculiar and treats non 0 values as equal so that non 0 values may be reshuffled in the process (as would be the case using quick sort). However, since Perl 5.8, the default sorting algorithm (merge sort) is inherently stable, so I would expect the order of non 0 values to be preserved. Is there anything that I am missing?

In reply to Re^3: move all 0s in an array to the beginning keeping other elements order same by Laurent_R
