I don't think it's valid. I suspect that when they recently changed judge's input for this program, they've used some incorrect solution to produce the output file.
I got my old program accepted again by printing "Possible" if it's possible to find expression that yields either +23 or -23.

Numbers will be positive. But somebody said 23 and -23 both should be correct which is actually the same, just altering the + and -.

10344(23 out of 5 ).

Postby TISARKER » Thu Dec 22, 2005 4:42 pm

Are u getting wrong answer for 10344 (23 out of 5 ).
Try following hints.

Code: Select all
if value==23 or value==-23 print " Possible"
Otherwise print "Impossible\n".
Another tricky is Value may be long
Thanks :lol: :wink: :D :) :P
