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 ?

Your input contains leading blanks, but statment says:
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

Best regards

Can anybody give me so correct test inputs? I got about 20 WA already I'm so desperate now.

What I knoe is the inputs does not have + sign in the front, expression must begin with a letter and there are no two consecutive + or - signs.

Plz help!!!!!!!

Hello!

I've received WA many times.

Anyone could write the correct output for this input, please.

The first case is problematic. Obviosly the result is 0, but it involucrates the same cell. Which is the correct interpretation?

My program returns:
Thanks
