Problem Statement
Compute the n-th Catalan number for n
Input Format
One integer n.
Output Format
One integer.
Constraints
0
Code Solution
This explanation is written for learning purposes and to help beginners understand the concept clearly.
Use formula Cn = (1/(n+1))*C(2n,n). Compute using integer nCr then divide by (n+1).
Common Mistakes
- Misreading input/output format.
- Not handling constraints and edge cases.
- Off-by-one errors in loops.
- Forgetting to reset variables between test cases (if any).
