The Time in Words

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

Details

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 timeInWords function which prints the time in words for the input given in the format described. The function has the following parameters:

• h: an integer representing hour of the day
• m: an integer representing minutes after the hour

Constraints

• 1 <= h <= 12
• 0 <= m < 60

Examples

timeInWords(5, 47) ➞ thirteen minutes to six
timeInWords(3, 00) ➞ three o' clock
timeInWords(7, 15) ➞ quarter past seven
timeInWords(5, 30) ➞ half past five
timeInWords(5, 01) ➞ one minute past five
