Problem B. Bad LaTeX
*****
All subscripts and superscripts will appear with integers with the exact format "X_{Y}" or "X^{Y}" and they will not be nested. In addition, every digit is surrounded by other digits, letters or spaces, with the subscripts/superscripts being the only exception to this. Numbers won't have leading zeros.
