Please program in C

Define a sequence of integers, Fib3 as follows: Fibs (1) Fib3 (n) -Fib3 (2) = = Fib3(n-1) Fib3 (3) = 1, Fib3 (n-2) Fib3 (n-3) for n3 Write the definition of a function that takes a an integer, n, as its argument and returns the value of Fib3(n). You can assume that the value of the argument is greater than 3
