Just one mistake

Do cout << (dp[n][0]+dp[n][1])%mod << endl;

@Jatin-Arora-2232866133621749 it is not mentioned in the problem statement to take mod of the answer, so no need to take mod here.
in your earlier version version of your code just use long long int to store your dp array.
look at this i have updated it in yours https://ide.codingblocks.com/s/243869
