Interview Prompt
You're scanning a column of integer ids pulled from a data export, arriving unordered and with repeats. Return the length of the longest run of consecutive integers present anywhere in the column, where consecutive means each value is exactly one more than the one before it. An empty column has a longest run of zero.
