Ans. 
The output will be 23323
• The DivideNumber method recursively divides the input number by 10 until it is less than 10

• The Console.Write statement prints the result of n/10 each time the method is called

Q1. 
Nth Fibonacci Number Problem Statement
Calculate the Nth term in the Fibonacci sequence, where the sequence is defined as follows: F(n) = F(n-1) + F(n-2), with initial conditions F(1) = F(2) = 1.
Input:
...read more
Ans. 
The program calculates the Nth Fibonacci number using a recursive formula.
• The Fibonacci series starts with 1, 1, and each subsequent number is the sum of the two preceding numbers.

• The program uses a recursive function to calculate the Nth Fibonacci number.

• The time complexity of the program is O(2^N), which can be optimized using memoization or dynamic programming.
