WA in DYNAMO

https://www.codechef.com/viewsolution/34002444

in my solution i have taken b+c and d+e as some value x and for printing s i do a+2*ans where ans=10^n and for printing c and e i do c=ans-b and d=ans-d .
when i submit it says wrong answer (-1.000) what does this mean
PS:- i have not solved any interactive problem in the past and was trying this out so i can work around how to deal with the long challenge covid sampling problem .

Can someone help me in this problem?

it is due to violation of constrains ,your program is violating question constraints.
