it uses your client's specified local time zone to determine whether or
not DST is in effect.
SET TIME ZONE 'America/New York';

hi,
you should use something similar to 'merge sort'
but only if your input is sorted (m_bx expects this)
if your subjects (numbers) are not going beyond a certain limit eg(65535)
take up an array and filter
you can generate a poly for array B's roots, and calculate A's points
-where it's 0,
