After losing the election for CEO of MCPT to Erfan, Theodore, furious of his loss, has decided to sue MCPT over voter irregularities. In his case, Theodore argues that a candidate gaining more than one consecutive vote is evidence that the voting machine has been tampered with (an irregularity) and only ~1~ should be counted.

To see if this case's merits should be heard, the court has asked you to perform an audit using Theodore's description of an irregularity and to report the new totals.
