The Time in Words

https://www.hackerrank.com/challenges/the-time-in-words/problem

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

5:00 -> five o' clock 5:01 -> one minute past five 5:10 -> ten minutes past five 5:15 -> quarter past five 5:30 -> half past five 5:40 -> twenty minutes to six 5:45 -> quarter to six 5:47 -> thirteen minutes to six 5:28 -> twenty eight minutes past five

At minutes = 0, use o'clock. For 1 <= minutes <= 30, use past, and for 30 < minutes use to. Note the space between the apostrophe and clock in o' clock. Write a program which prints the time in words for the input given in the format described.
