Question 9: Coding with Nodes

a. Provide a complete method to traverse a linked list ofStrings, headed by firstNode, and determine if eachStringcontains a specific character.

b. Provide a complete method to determine if a linked list of Integers, headed by firstNode, contains any two values repeated. For example, 4->2->2->3 would return true and 3->2->4->2 would return false.

c. Provide a complete method that takes in a linked list of Integers (headed by firstNode) and an int array and merges them together into an array using an alternating merge.
