Seller Classification
Seller Classification
You are given the number of sellers and, for each seller, a set of feedback ratings. Your task is to classify each seller based on the average of their feedback ratings. The average for a seller is computed as
$$ \text{average} = \frac{\sum_{i=1}^{n} \text{rating}_i}{n} $$
and the classification rules are as follows:
- If the average rating is at least 50, the seller is classified as
Excellent
. - If the average rating is non-negative but less than 50, the seller is classified as
Good
. - If the average rating is negative, the seller is classified as
Poor
.
Read the input from stdin
and output the classification for each seller to stdout
, one per line.
inputFormat
The first line of input contains an integer T
representing the number of sellers. The next T
lines each correspond to a seller. Each of these lines starts with an integer n
representing the number of feedbacks followed by n
integers indicating the feedback ratings.
For example:
3 4 50 60 70 80 3 10 -10 30 2 -20 -30
