i'm trying this problem for a long time now. i'm new in dp. here is my C++ code:
#include<stdio.h>
#include<string.h>


int memo[600][20000];
int que[600],qi;
char side[5][600],ms;

int load(int port_sz,int star_sz,int ci)
{
if(ci>=ms)
{
strcpy(side[1],side[0]);
ms=ci;
}
if((port_sz<0 || star ...

i've used a class for the BigInts and it's operators but i'm getting WA. can anyone help me with any suggestion or any critical input
