( #3333=superdoc: print w/ replies, xml ) Need Help??
I've a hash of hash like,
Year = { 2007 = { 01 => 07, 02 => 34, 10 => 24, 09 => 14, } 2008 = { 01 => 11, 02 => 64, 03 => 20, 09 => 13, } }
where I want to get the maximum and minimum of all years. So, result will be 02 in 2008 is maximum and 01 in 2007 is the minimum.
I've tried to get this in different ways. But, the code is larger like writing in conventional languages. Someone help me write this smarter.
