Write a program that receives one text argument and prints it backward, followed by a newline.

• The program expects exactly one argument after the executable name.
• Print the characters of that argument in reverse order.
• Preserve every byte from the argument: letters, spaces, digits, and punctuation are all reversed the same way.
• Always finish valid output with a newline.
• If the program does not receive exactly one argument (argc must be 2), print wrong number of arguments followed by a newline.
• Use only write.
