I've been trying to solve this problem and i always get WA. I even tried to treat cases such spaces in the beginning and in the end of the lines, or numbers "0000000" or "000055543543", but still WA. Here is my code:

[pascal]
type bignr=
record
len:byte;
v:array[0..200] of byte;
end;
var n,m ...

Eric try this:

100 100
0 100
0 0

This problem askes you to calculate the cubic root USING THE EXPLAINED approxximation method. It is valid to ignore (dx)^2, because the dr. did it, when calculating. On the other hand i don't understand what happened to the judge program not accepting solutions with long double. Anyone using Pascal ...

I tried to solve the problem using double in Pascal with the same formula. I got WA. Any hints? For cubic root i used trunc(exp((1/3)*ln(n))). A tried with int instead of trunc, too. Help please.
