HI, It is really really bad and bit rusty for me to get TLE in this problem, well, anyone can suggest me what to modify my code inorder to get it with reasonable time.............
Code: Select all
#include<iostream>
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<math.h>
#include<algorithm>
using namespace std;
#define MAX 2000000

}

f=strlen(first);
s=strlen(sec);
reverse(first,F);
reverse(sec,S);
for(now=0,extra=0;(now<f && now<s);now++)
{
sum=(F[now]-'0') + (S[now]-'0') + extra;
Res[now]=sum%10 +'0';
extra= sum/10;
}
for(;now<f;now++)
{

strcpy(Res,"0");

After a while, I realized that you did not include "0 0" at the end of your test input 
Help pls!!!
