Rank race finishers without touching the bib-number order
RANK usually counts down from the biggest number, but a stopwatch makes the smallest one the winner — that's what its order argument is for.
Task:
You handle results for the Riverside Running Club's monthly 10K. Runners are logged in the order they crossed the start line, and the results board keeps that order — only the rank column changes. Work out each runner's finishing position in column C, with the fastest time taking first place.
The daily challenge is part of Pro
A new exercise every morning, plus every day that came before it — a back catalogue that grows by one a day, whether or not you were here for it.
