The wall of a fruit

A class measures the three layers of the pericarp in some fleshy fruits, in millimetres. You will find the mesocarp share, list the fruits with a thick fleshy layer, and draw a bar chart.

The idea. Each record is a tuple: the name, the epicarp, the mesocarp and the endocarp. The pericarp is the sum of the three layers.

Your tasks.

1. Write share(epi, meso, endo). It returns the mesocarp as a percentage of the pericarp.
2. Set fleshy to the names of the fruits whose mesocarp is more than $65$ per cent of the pericarp, in the order of the records.
3. Set best to the name of the fruit with the largest mesocarp share.
