You are given an integer 'n'. Calculate the sum of even and odd digits of 'n', represented in decimals.

Even and odd do not refer to the position of the digit but to the polarity of the digit.

Return the answer in the form of an array of size 2, such that the 0th index represents the even sum and the 1st index represents the odd sum.

Example:

Input: 'n' = 1986.

Output: [14, 10]

Explanation: Even digits are 8 & 6, and odd digits are 1 & 9. The sum of even digits = 14, and the sum of odd digits = 10.

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.
