C only (not C++)

(easy way if possiple)

Develop a C recursive function that accepts an integer N. The function should calculate and return the result of the following function: f(N) = 1 + 1/2! + 1/3! + ... + 1! Write a C program that reads an integer value. The program should call the function above and then print the result on the screen with two decimal point format (i.e. 12.34). Output example: Enter an integer: 5 f(5) = 1.72
