Write a program in C# to perform a bird survey to count the number of birds of each species in an area. Create a class BirdSurvey that is a linked list. The linked list can be one way linked list, circular linked list or a doubly linked list; whichever you choose.

BirdSurvey should have the following operations in addition to those normally found in your linked list class:

1. add(bird) adds the bird species bird to the end of the list, if it is not already there. sets its count to 1; otherwise, adds 1 to the count for bird.

2. getCount(bird) returns the count associated with the species bird. If bird is not on the list, returns zero.

3. getReport() displays the name and count for each bird species on the list.

You will write a program that uses BirdSurvey to record the data from a recent bird survey. Use a loop to read bird names until done is entered. Illustrate the use of each of the methods mentioned above, with the last being a Report of all the species of birds entered and the count for each species.
