HI, can anyone explain why this case (x * -y) is valid?
I think there should be only one operator between two values.

my Acc code get WA for this new entry in test data.

thanks.

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.

Yes Got Acc using the condition (x*-y).....
but why it is valid because the number will be positive...

Thank's for Reply

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

i understant that...
But for frist time i missed it.... ok now acc..

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
