No matter when I used double or long double, my code still got TLE.

Opt[Now][j][0] = Opt[Pre][j][0] + Opt[Pre][j][1] + Opt[Pre][j][3];
Opt[Now][j][1] = Opt[Pre][j - 1][0] + Opt[Pre][j - 1][2] + Opt[Pre][j - 1][1];
Opt[Now][j][2] = Opt[Pre][j][2] + Opt[Pre][j][3];
Opt[Now][j][3] = Opt[Pre][j - 1][2] + Opt[Pre][j - 1][3];

I had to write a Pascal code using extended and got AC.
Could anyone tell me how to AC in C++?

I know solution which can be written on all allowable languages.
I suppose, this solution won't get TLE. Becouse it is O(1).
