Write code in C++, C# or Python to solve the following problem: Instead of a regular Fibonacci number, you are supposed to calculate a special one as follows: F(n) = F(n-1)+ 2 * F(n-2) + 3 * F(n-3) As an example, if F(0) = F(1) = F(2) = 1, then we have: F(3) = F(2) + 2 * F(1) + 3 * F(0) = 1 + 2 + 3 = 6 F(4) = F(3) + 2 * F(2) + 3 * F(1) = 6 + 2 + 3 = 11 Given F(0), F(1), F(2), and N, your job is to calculate F(N). Input Format First number is F(0), second number is F(1), third number is F(2), and last number is N. Example input: 1 1 1 4 Constraints NA Output Format Print the Nth special Fibonnaci number. Example output: 11

Question
Write code in C++, C# or Python to solve the following problem:
Instead of a regular Fibonacci number, you are supposed to calculate a special one as follows:
F(n) = F(n-1)+ 2 * F(n-2) + 3 * F(n-3)
As an example, if F(0) = F(1) = F(2) = 1, then we have:
F(3) = F(2) + 2 * F(1) + 3 * F(0) = 1 + 2 + 3 = 6 F(4) = F(3) + 2 * F(2) + 3 * F(1) = 6 + 2 + 3 = 11
Given F(0), F(1), F(2), and N, your job is to calculate F(N).
Input Format
First number is F(0), second number is F(1), third number is F(2), and last number is N.
Example input: 1 1 1 4
Constraints
NA
Output Format
Print the Nth special Fibonnaci number.
