Write a program to input a natural number less than 1000 and display it in words. Test your program on the sample data and some random data.

Sample input and output of the program.

Examples

``````Input: 29
Output: TWENTY NINE

Input: 17001
Output: OUT OF RANGE

Input: 119
Output: ONE HUNDRED AND NINETEEN

Input: 500
Output: FIVE HUNDRED
