Hi @Rajat-Sharma-2078329489142103
In this question you have to print ans%1000000007; because ans can be a large number and can go out of the range of long long int. So you need to make a single change in you code at line 8 like this :
a[i]=(a[i-1]+a[i-m])%1000000007;

Here is your corrected code :

If your doubt is clear mark it as resolved.
