    Here is a section of code you can use just for converting the numbers 1-29 into words in python. Normally you could use :

    pip install num2words
from num2words import num2words as n2w

    but the environment on hackerrank doesn't allow the "pip install num2words" command. So I put together this to use instead for this challenge.

    def n2w(n):
    words = {
        1: "one",   2: "two",     3: "three",  4: "four",    5: "five",
        6: "six",   7: "seven",   8: "eight",  9: "nine",   10: "ten",
        11: "eleven", 12: "twelve", 13: "thirteen", 14: "fourteen", 15: "fifteen",
        16: "sixteen",17: "seventeen",18: "eighteen",19: "nineteen"
    }
    if n <= 19:
        return words[n]
    base = "twenty"
    return base if n == 20 else base + " " + words[n - 20]

    My Java solution with constant space and time complexity:

    private static final String[] NUM_WORDS = {
        "", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten",
        "eleven", "twelve", "thirteen", "fourteen", "quarter", "sixteen", "seventeen",
        "eighteen", "nineteen", "twenty", "twenty one", "twenty two", "twenty three",
        "twenty four", "twenty five", "twenty six", "twenty seven", "twenty eight",
        "twenty nine", "half"
    };

    public static String timeInWords(int h, int m) {
        if(m == 0){
            //use o' clock
            String hour = NUM_WORDS[h];
            return hour + " o' clock";
        }
        if(m <= 30){
            //use past
            String minutes;
            if(m == 1)
                minutes = "one minute";
             else if(m == 15)
                minutes = "quarter";
            else if(m == 30)
                minutes = "half";
             else
                minutes = NUM_WORDS[m] + " minutes";
            
            String hour = NUM_WORDS[h];
            return minutes + " past " + hour;
        }
        else{
            //use to
            String minutes;
            if(60 - m == 1)
                minutes = "one minute";
             else if(60 - m == 15)
                minutes = "quarter";
             else
                minutes = NUM_WORDS[60 - m] + " minutes";
                
            String hour = NUM_WORDS[(h < 12) ? h + 1 : 1];
            return minutes + " to " + hour;
        }
    }
