12.The Daily Report

The owner wants a short report of today in ~/report.txt, with exactly three lines:

text

1. the number of sales (the lines with SALE)
2. the number of ERROR lines
3. the best-selling product and its count, from the SALE lines

The columns of ~/till.log are separated by spaces: time, type, product.

Something unclear, wrong or missing?
