Problem 1946. Fibonacci-Sum of Squares

Given the Fibonacci sequence defined by the following recursive relation,

  • F(n) = F(n-1) + F(n-2)
  • where F(1) = 1 and F(1) = 1

determine the sum of squares for the first "n" terms.

For example, n=5 --> 1^2 + 1^2 + 2^2 + 3^2 + 5^2 = 40.

  • INPUT n=5
  • OUTPUT S=40
