The Time in Words - HackerRank Solution

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.
