You can use exists($hash{$k2}) to test if %hash contains the key $k2. If exists, $hash{$k2} will return the value previously set; undef otherwise.

Good Evening,
I started working on the 17x17 4-colouring challenge, and I ran into a bit of an I/O snag.

The MLIB_USHORT type entries are indexed from 0 to 65535. The MLIB_INT type entries are indexed from -2147483648 to -1, and then from 0 to 2147483647. RETURN VALUES
