A robot uses a laser sensor to detect the distance of obstacles. The laser has noise that produces two readings that are too big and three readings that are too small. Write a matlab function, called avg_dist, to find the average distance reading after dropping the two largest values and the three smallest values. The function has one input parameter, the list of distances. The function has one output, the average distance after dropping the appropriate values.

Test Case: D = [33 33 6 38 32 4 37 31 37 38 60 9 67 33 37] avg_dist(D) % Should return 34.9
