Given two arrays ‘ARR’ and ‘BRR’ of size ‘N’ and ‘M’ respectively. Your task is to sort the elements of ‘ARR’ in such a way that the relative order among the elements will be the same as those are in ‘BRR’. For the elements not present in ‘BRR’, append them in the last in sorted order.

For example

Consider the arrays as ARR = { 9, 5, 8, 4, 6, 5 } and BRR = { 8, 4, 5 }
The output for the above example  is { 8, 4, 5, 5, 6, 9 }.

Note:

Elements of ‘BRR’ are non repeating.

Difference between equal and equals.

Difference between overloading and overriding.

What is inheritance. 

What types of inheritance are supported by java.

1. What is primary, candidate and foreign key.
2. Write a query to join three tables.

You are given an integer ‘N’, your task is to find and return the N’th Fibonacci number using matrix exponentiation.

Since the answer can be very large, return the answer modulo 10^9 +7.

Fibonacci number is calculated using the following formula:

F(n) = F(n-1) + F(n-2), 
Where, F(1) = F(2) = 1.

For Example:

For ‘N’ = 5, the output will be 5.
