5 - Keep the Beat
	The choir leader missed rehearsal and you are needed to help the substitute count out the beat.  With rare exceptions, a piece of music comes with a specific “time signature” consisting of two numbers.  The first number indicates the number of beats in a measure.  The second number (not relevant in this problem) indicates what kind of note takes one beat.  For example, marches are 2 4 time, so they count out as 1 2 1 2 1 2 etc.  Walzes are 3 4 time, and count out as 1 2 3 1 2 3 1 2 3 etc.
Input:
	There may be multiple cases, one per line.  The last line has 0  0.  A case consists of the two number time signature.
Output:
	For each case display at least the first 20 beats, or more if needed to finish a measure.   Count it out as in the sample.
