You must call get for each morsecode part. so get("....") for "H", then get() for the "E", and so. only one sequence for one character is translated

I agree, the instructions should be more clear on this..

I have a question.

For the example "HEY JUDE", the method decodeBits() should return "···· · −·−− ·−−− ··− −·· ·"?

If I put
public static String decodeBits(String bits) {
return "....";
}
and then run the test, the message is "Expected: is "HEY JUDE" but: was "H""

If I put
public static String decodeBits(String bits) {
return "···· · −·−− ·−−− ··− −·· ·";
}
and then run the test, the message is "Expected: is "HEY JUDE" but: was "null""

But i see that the tests call both MorseCodeDecoder.decodeMorse AND MorseCodeDecoder.decodeBits

Thanks.

Look at the follow example:
[25,25,50,25,25,100,50]

When the bag was equal = 125, in the line they remain [...,100,50]

If to the person of 100dollars you give them 1bill-50dollars and 1bill-25dollars, you can given back to the last person
But if to the person of 100dollars you give them 3bill-25dollars, you can't given back to the last person

In conclusion, the priority of bills to give back was not defined

That such a bug does not exist !
Always the person should receive as much money as possible.

Sorry.

Look at the follow example:
[25,25,50,25,25,100,50]

Following your opinion... when the bag was equal = 125, in the line they remain [...,100,50]

If to the person of 100dollars you give them 1bill-50dollars and 1bill-25dollars, you can given back to the last person
But if to the person of 100dollars you give them 3bill-25dollars, you can't given back to the last person

In conclusion, the priority of bills to give back was not defined

bag=[]
25 in
bag=[25]
50 in
25 out
bag=[50]
50 in
no 25 can be given back
you should know: 50!= 25x2
