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. 
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).

Q3. What is a merge join in SQL?
Ans. 
A merge join in SQL is a method of combining two sorted datasets by matching corresponding rows based on a specified condition.
• Merge join is used when joining two large datasets that are already sorted.

• It is more efficient than other join methods like nested loop join or hash join for sorted datasets.

• The join condition must be an equality condition.

• Example: SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.i

Ans. 
Implement a function to multiply two sparse matrices and return the resulting matrix.
• Create a function that takes two sparse matrices as input and returns the resulting matrix after multiplication

• Iterate through the non-zero elements of the matrices to perform the multiplication efficiently

• Handle the edge cases such as empty matrices or matrices with all zero elements

• Ensure the dimensions of the matrices are compatible
