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.

HI, can anyone explain why this case (x * -y) is valid?

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.

i got the same output as you get....and WA...any more I/O...
but i read from other thread that some one says that the expression can be (x*-y) is it valid......?? My programme not support it...

Thank's in Advance
Rocky

[Rocky]

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 -.

[Rocky]

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

Thank's Again

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
