Plantain is a weed found on farms. If the percentage of plantain is low, the farm is considered healthy - suitable for crop growth the grazing by live stock. A farmer takes readings each year to determine the plantain saturation (as a percentage) of some paddocks on their farm. Your task is to process the plantain saturation data collected from the past three years and determine if a farm is
unhealthy. If the crops are
unhealthy, you must determine if the farmer should
resow their land.
- If the average (arithmetic mean) plantain saturation reading is \ge 12\% for each of the past three years then the farm is deemed to be
- If the farm is
unhealthyAND 50% or more of paddock readings for the most recent year have plantain saturation \ge 25\%, then the farmer should
- A farm is
healthyfor all other situations.
The first line will contain a single integer, N, the number of readings taken in the most recent year (1 \le N \le 200). The second line will contain N space-separated integers, the plantain saturation (as a percentage) for each paddock sampled that year. Each saturation reading will be an integer between 0 and 100 (inclusive).
This input format is repeated for the data collected in the two prior years. N might be different for each year.
You should output a single line containing either
resow, based on the above criteria.
- Subtask 1 (40%): It is guaranteed that the farm will always be either
- Subtask 2 (60%): No further restrictions apply.
