/// Calculate Fibonacci series of the given values by using array

/*
Fibonacci series,
Let, initial1st_no=0, 2nd_no=1  [first & second number are always constant]
Formula:
               Fibonacci Value (n) = Summation of previous 2 values
Example:
               Fibonacci Value (0) = 1st_no = 0
               Fibonacci Value (1) = 2nd_no = 1
               Fibonacci Value (2) = 1st_no + 2nd_no = 0+1 = 1  (3rd_no)
               Fibonacci Value (3) = 2nd_no + 3rd_no = 1+1 = 2 (4th_no)
               Fibonacci Value (4) = 3rd_no + 4th_no = 1+2 = 3  (5th_no)
               Fibonacci Value (5) = 4th_no + 5th_no = 2+3 = 5  (6th_no)
               Fibonacci Value (5) = 4th_no + 5th_no = 3+5 = 8  (7th_no)
