Implementation

○●
○○

For more information please see wikipedia

Printing one character is very important and should be done at first.

There are special signs to modify how system is working:

• Letter Sign - all next characters will be small letters
• Capital Sign - next character will be capital (only one)
• Double capital sign - all next characters will be capital
• Number Sign - all next characters will be numbers

All new words are small characters as default. Numbers characters need special number sign so 123 abc you can write as <NUMBER_SIGN>abc abc Interpunction characters do not need special signs so 1,23 you can write as <NUMBER_SIGN>a,bc
