Number to English Words

Given an integer n where \( -999{,}999 \le n \le 999{,}999 \), convert it to its English word representation.

If the number is negative, the output should start with the word minus. The words should be in lower-case and numbers should be expressed in their natural English words.

For example:

• Input: 123 → Output: one hundred twenty three
• Input: -45 → Output: minus forty five
• Input: 500034 → Output: five hundred thousand thirty four

Note: Your program should read the input from stdin and print the output to stdout.
