Find a node in a LinkedList In Java:

1. (2 pts) Define the nodes in the LinkedList.

2. (2 pts) Create the LinkedList using the ListNode class.

3. (4 pts) Create a method to find a node with given value in a LinkedList. Return the value is this value exists in the LinkedList. Return null if not exists.

4. (2 pts) Use these two examples to test your method.

Example 1:

Input: 1 -> 2 -> 3, and target value = 3

Output: 3

Example 2:

Input: 1 -> 2 -> 3, and target value = 4

Output: null

4) A ray of white light is incident on a prism surface at some angle, so that you see a rainbow coming out from the other side. Order the colors with respect to their individual degrees of refraction, that is, by their refraction angles. (order them from 1 to 4)

           - 1. 2. 3. 4. Yellow

         - 1. 2. 3. 4. Red

         - 1. 2. 3. 4. Blue

         - 1. 2. 3. 4. Green
