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]

Nice — solving the same problem in five languages is a great way to compare idioms. Below I’ll give concise, actionable feedback you can apply to each implementation (correctness, edge cases, style, tests), plus language-specific tips. 11xplay Sign Up

My java solution. Not all tests pass and i don't understand why. If i test them by hand they pass, but sending solution makes them not pass (for example test 2)

class Result {

/*
 * Complete the 'timeInWords' function below.
 *
 * The function is expected to return a STRING.
 * The function accepts following parameters:
 *  1. INTEGER h
 *  2. INTEGER m
 */

 private static final String[] NUMBERS = {
    "", "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) {
// Write your code here
StringBuilder b = new StringBuilder();
if(m > 0 && m <= 30) {
    System.out.print(NUMBERS[m] + " past " + NUMBERS[h]);
    b.append(NUMBERS[m] + " past " + NUMBERS[h]);
} else if(m > 30) {
    System.out.print(NUMBERS[60-m] + " minutes to " + NUMBERS[h+1]);
    b.append(NUMBERS[60-m] + " minutes to " + NUMBERS[h+1]);
} else {
    System.out.print(NUMBERS[h] + " o' clock");
    b.append(NUMBERS[h] + " o' clock");
}
return b.toString();
}

}
