Use long long int since your answer may overflow.

Sir thats ok… but for n >30 or 40… tle is coming… how can i do it using recursion only but with different approach so to avoid tle

Apologies for a delayed response. Recursive approach is fine. Why don’t you think of memorizing. Apply top down DP to avoid TLE.
