Back-to-the-past

Back to the Past Ivan is 18 years old and receives an inheritance that consists of X money and a time machine. He decides to return to 1800, but does not know if the money will be enough to live without working. Write a program that calculates if Ivan will have enough money to not have to work until a particular year (inclusive). Assuming that for every even (1800, 1802, etc.) year he will spend 12 000 dollars. For every odd one (1801, 1803, etc.) he will spend 12 000 + 50 * [the age he will have reached in the given year]. Input Data The input is read from the console and contains exactly 2 lines: • Inherited money – a real number in the range [1.00 … 1 000 000.00]. • Year, until which he has to live in the past (inclusive) – integer number in the range [1801 … 1900]. Output Data Print on the console 1 line. The sum must be formatted up to the two symbols after the decimal point: • If money is enough: o "Yes! He will live a carefree life and will have {N} dollars left." – where N is the money that will remain. • If money is NOT enough: o "He will need {М} dollars to survive." – where M is the sum that is NOT enough.
