Hello Programmers, In this post, you will know how to solve the HackerRank The Time in Words Solution. This problem is a part of the HackerRank Algorithms Series.
One more thing to add, don’t directly look for the solutions, first try to solve the problems of Hackerrank by yourself. If you find any difficulty after trying several times, then you can look for solutions.
HackerRank The Time in Words Solution
Task
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 minute 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.
Function Description
Complete the timeInWords function in the editor below.
timeInWords has the following parameter(s):
- int h: the hour of the day
- int m: the minutes after the hour
Returns
- string: a time string as described
Input Format
The first line contains h, the hours portion The second line contains m, the minutes portion
Constraints
- 1 <= h <= 12
- 0 <= m < 60
Sample Input 0
5 47
Sample Output 0
thirteen minutes to six
Sample Input 1
3 00
Sample Output 1
three o' clock
Sample Input 2
7 15
Sample Output 2
quarter past seven
