Given the time in numerals we may convert it into words, as shown below:

5:00 => five o' clock
7:29 => twenty nine minutes past seven
5:01 => one minute past five
5:10 => ten minutes past five
5:30 => half past five
5:45 => quarter to six
5:47 => thirteen minutes to six

Write a program which prints the time in words for the input given in the format mentioned above.
