Description

英語是現在世界第一大語言，所以學好英語是very important， 但是寧波大學的某個大牛說：“我不怕，我可以寫一個程序讓各種語言 快速轉換。”哎呀，學編程的，惹不起...溜...┈━═☆ 咱不是大牛，但有追逐大牛的夢想，大牛的偉大程序不是隨便能盜版出來的， 我們就做一個簡單的翻譯器，把阿拉伯數字轉換為英文輸出。

Input

小于10000的非負阿拉伯數字整數n。

Output

對應的英文，如樣例，一個一行。

Sample Input

3923 5021

Sample Output

three thousand nine hundred twenty three five thousand twenty one
