I always have WA8, can you give me some tips about this test?

using System;
namespace t1000{
    class Program{
        public static void Main(string[] args){
            string[] s = Console.ReadLine().Split(' ');
            Console.WriteLine(int.Parse(s[0]) + int.Parse(s[1]));
        }
    }
}

It must be mentioned that two dice are considered equal if the numbers of points on corresponding faces are equal regardless of the orientation of the points on each face. For example, if you superimpose two dice and the numbers of points coincide but two corresponding faces look like this:
#..       ..#
.#.  and  .#.
..#       #..
then the dice have the same schemes.

I cant understand my mistake for TLE14.
My code
var

    z2,z1,a,i,f,p,code: integer;z,n:int64;
    ch:char;
begin
    readln(s);

    for i:=1 to n do
    begin
        readln(s2);
        if s2[1]='p' then
        begin
        a:=13;z1:=0;z2:=0;
            while s2[a]<>' ' do
            inc(a);
         val(copy(s2,13,a-13),z1,code);
         val(copy(s2,a+1,length(s2)-1),z2,code);
             z:=z2-z1+1;
             if z2>length(s) then z2:=length(s);
            s1:=copy(s,z1,z);

             f := 1;
             p:=1;
             while (p<=length(s1)div 2)and(f<>0)  do
             if (s1[p] <> s1[length(s1)-p+1]) then
             begin
                  writeln('No');
                  f := 0;
             end else
             p:=p+1;

             if f = 1 then
             writeln('Yes');
        end else
        begin
        a:=8;z1:=0;
           while s2[a]<>' ' do

                 Val(copy(s2,8,a-8),z1,code);

I added in the package line but if I left that in, it would give me a compilation error, why is that? And this code runs perfectly fine in Netbeans but the judge gives a compilation error

I solved the equation x(x-1) % 10^i = 0 for every i>1 and i<=n by linear algorithm, using roots for i-1.

Test 2 is something like this

Good luck!

Use   if(c> 8000000000LL || c< -8000000000LL)  break ; this line in BInary search...
