You have to take modinverse to calculate nCr . Your current approach is almost correct just add this thing to get your solution accepted.

what is modinverse sir??

Whenever you are asked to calculate a/b it can vary depending upon compiler. So we use modinverse to find (a%m / b%m )%m to get a fixed integer value.
