The `tree` command prints all files/directories contained in the current directory as a tree. If we run `./tree` from the cs214 directory, we should see:```.- hw1 - factor.c - grep.c - monster.c - sort.c - uniq.c- hw2 - find.c - ls.c - Makefile - tree.c```The first line of output is always “.” to denote the current directory. `tree` recurses into directories to print all files/directories within them. For each subdirectory, two spaces of indentation are added. For example, if we had a file `hw1/test/src/foo.c`, `tree` would print:```.- hw1 - test - src - foo.c```Files/directories within each subdirectory should be sorted with the same lexicographic order as in `ls`.

In Linux, a tree is defined as a recursive directory listing program that generates a depth-indented…

Java code that eliminates the binary search's node with the lowest value. returns a reference to its element from a tree. If this tree is empty, it raises an EmptyCollectionException. If the tree is empty, returning a reference to the node with the fewest values produces an EmptyCollectionException.

Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts Code provided in the assignment ItemNode.java:

If the tree is empty, returning a reference to the node with the least value produces an EmptyCollectionException.
Change the insert and _insert methods accordingly to comply with the new format. - If a new word is inserted that has a matching sorted order of its letters as an existing Node, do not insert a new Node.
