Write a program to delete a node from a LinkedList. You should write two methods:

Delete an element based on its value.

boolean deleteByValue(int data)

Delete an elemnt based on its index.

boolean deleteByIndex(int index)

Example: Your LinkedList has 4 elements: 10, 20, 30 and 40. deleteByValue(30) will remove 30 from the list and list would look like 10, 20, 40. deleteByIndex(1) will delete 20 from the list and the list would look like 10, 40.
