1 orange or grapefruit

I guess the fruit is grapefruit, or oranges?
If large red, probably grapefruit; on the contrary may be orange.
How to determine this fruit is orange or grapefruit?
One way is to look at its neighbors.
In these three neighbors, oranges more than grapefruit, so the fruit is likely to be orange. This is K-nearest neighbor algorithm.
