PROBLEM 10:
Mr. Uncle is very happy with the skills of PS & CP students. He would like you to solve a new problem that takes amount as integer num in input and output its value in words. You are required to generalize the solution for any amount. Write a C Program for solving this problem.
INPUT SIMPLE:
Sample Input
Sample Output
2000
Two Thousand Rupees
545
Five hundred and Forty Five Rupees
1300
Thirteen Hundred Rupees
100000
One Hundred Thousand Rupees 1000000000

One Billion Rupees
