    c++ solution:

    string encodeDigit(int n) {
    switch (n) {
        case 1:
            return "one";
        case 2:
            return "two";
        case 3:
            return "three";
        case 4:
            return "four";
        case 5:
            return "five";
        case 6:
            return "six";
        case 7:
            return "seven";
        case 8:
            return "eight";
        case 9:
            return "nine";
        default:
            return "";
    }
}

string encodePreTwenties(int n) {
    switch (n) {
        case 10:
            return "ten";
        case 11:

    }
    
    if (minutes == 20) {
        return "twenty minutes";
    }
    
    return "twenty " + encodeDigit(minutes - 20) + " minutes";
}

string timeInWords(int h, int m) {
    if (m == 0) {

    Live by the library, die by the library I guess.

    I was working with Swift, and Foundation has a spell out style number formatter. So I decided to use it.

    Passed all the "open" test cases, failed two of the locked ones. Made the example section into another batch of test cases, and low and behold I was generating "twenty-eight minutes past five" and the example had no dash.

    So anyone else deciding to save time by using the built in Foundation number formatter (hey if it were a real world job I would be upset at a PR trying to spell out numbers and not just using the libary without good reason!) should be aware they need to post process hyphens into spaces....

    My python solution:

    def timeInWords(h, m):

    nums = ["one",'two','three','four','five','six','seven','eight','nine','ten','eleven','tweleve', 'thirteen', 'fourteen',15,'sixteen', 'seventeen', 'eighteen','nineteen','twenty','twenty one','twenty two','twenty three', 'twenty four','twenty five','twenty six','twenty seven','twenty eight', 'twenty nine']

phrases = {0:"o' clock", 
       15:"quarter past", 30:'half past', 
       45:"quarter to", }
if m==1 and h==1:
    return 'one minute past one'
if m==0:
    return nums[h-1]+' '+phrases[m]
elif m==45:
    return phrases[m]+' '+nums[h]
elif m==15:
    return phrases[m]+' '+nums[h-1]
elif m==30:
    return phrases[m]+' '+nums[h-1]
elif 1<=m<=30:
    return nums[m-1]+' minutes past '+ nums[h-1]
else:
    k=60-m
    return nums[k-1]+' minutes to '+nums[h]
