Sorry I should have clarified, this is a sample output for breaches_per_month, not preprocess. Where my output follows the rules you defined: "The values for the median and MAD should be printed to standard output. When you have the median and MAD, you are to print a table of the months, where, against each month you list the number of incidents and then either "++", if the count is 1 median-absolute-deviation above the median (or more); "--", if the count is 1 median-absolute-deviation below the median (or less). If the count is within 1 median-absolute-deviation of the median don't add anything. "
