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