Can you give me a set of Test Data of Problem 215? Thank you.

I try to solve this problem but I got WA a few times - could anyone help me and send some IO data ?
I use simple grammar to evaluate cells values and I loop in sheet until I can evaluate any cells. Is this algorithm wrong ?

Sorry, dominik. Padding space in my output is wrong.

Good Luck. [/java]

Code: Select all

``No line of input contains leading blanks. No expression contains any embedded blanks. ``
And output format should be (for unevaluated)
<cell_name>: <cell_formula>

However I got Accepted now Maybe input contains spaces at start of formula - I don't know ... I found in my code some mistakes with signs of expressions.

Thanks Red Scorpion for help
