River BOD Pollution Report

Two rivers are sampled for 4 days. Store names in RiverNames and readings in RiverStats[1:4, 1:2] (rows are days, columns are rivers).

A day is moderately polluted when BOD is from 2 to 8 inclusive, and highly polluted when BOD is greater than 8. For each river output the average BOD rounded to 2 d.p., the moderate-day count, and the high-day count. Then output the river with the most highly polluted days (first river wins a tie).

Input: Two names, then 8 readings day-by-day (river 1 then river 2, four times). Output: Two river summaries, then the most-polluted name.

Example:
