C. In permutations and combinations, the term "n Cr" refers to n combinations taken r at a time. n! nCr = r! (n -r)! Write a recursive function to find the factorial of a number. Use the defined function to compute the term "nCr" for the following scenario: The values of 'n' and 'r' are stored in two parallel arrays of any user defined size. You have to Read the arrays n and r at run time. Compute n Crfor each corresponding terms in the array 'n' and 'r, and display it properly formatted. Also your program should print the current date and time using library functions.
