Linear lists

Information about the task:

• Element type: Char
• List type: Linear unidirectional
• Action: Remove from the list all the elements that precede and follow the specified value

Realize these functions for list:

1. list_create- for list creating
2. help - to show information about the app
3. list_insert- for inserting the value in the list
4. list_print- for showing content of the list
5. list_node_delete- for deleting the node with its value from the list
6. list_node_find - for finding the node with certain value
7. list_destroy - for list destroying
8. list_clear - for making the list empty
9. list_lenght - for defining list's lenght
10. list_task - for launching the action that is shown beyond

Realize these functions for iterator:

1. iterator_first - returns first node's value of the list if it exists
2. iterator_last - returns last node's value of the list if it exists
3. iterator_next - returns the value which is the next after inputted element

Algorithm of the solution of the task

• clear the list
• insert the definite element

How To Use

• 'add' - to insert the value to the list\n");
  Input the elements in this order:

1. The value to set up
2. The value after which you have to insert
   Note: if the value after which you want to insert doesn't exist, program should stop working
   For inserting the element to the list origin input in this way: 'value' '.'

• 'delete' - to remove the value from the list
• 'lenght' - to gain the list size
• 'task' - to start removing the elements that precede and follow the specified value
• 'print' - to print the list
• 'clear' - to make the list empty
• 'destroy' - to destroy the list
• 'exit' - to quit the application
