    Input:

    ...
  • Ans. 

    Calculate the Nth Fibonacci number efficiently using dynamic programming.

    • Use dynamic programming to store previously calculated Fibonacci numbers to avoid redundant calculations.

    • Start with base cases F(1) and F(2) as 1, then iteratively calculate F(n) using F(n-1) and F(n-2).

    • Ensure the input N is within the constraints 1 <= N <= 10000.

    • Example: For N = 5, the 5th Fibonacci number is 5 (1, 1, 2, 3, 5).
