Question

The language is Java

• Implement MyArrayList and MyLinkedList using MyList interface and
MyAbstractList as defined in Java Collection Framework. (5 points)
• Write code to partition a linked list around a value x, such that all nodes
less than x come before all nodes greater than or equal to x. If x is
contained within the list, the values of x only need to be after the elements
less than x. The partition element x can appear anywhere in the “right
partition”; it does not need to appear between the left and right partitions.

• For the following problem use your own created MyArrayList or MyLinkedList if needed. (10 points)

Given an array of words and a width maxWidth, format the text such that each line has exactly maxWidth characters and is fully (left and right) justified.

You should pack your words in a greedy approach; that is, pack as many words as you can in each line. Pad extra spaces ' ' when necessary so that each line has exactly maxWidth characters.

Extra spaces between words should be distributed as evenly as possible. If the number of spaces on a line do not divide evenly between words, the empty slots on the left will be assigned more spaces than the slots on the right.

For the last line of text, it should be left justified and no extra space is inserted between words.

Note:

• A word is defined as a character sequence consisting of non-space characters only.
• Each word's length is guaranteed to be greater than 0 and not exceed maxWidth.
• The input array words contain at least one word.

Example 1:

Input:

words = ["This", "is", "an", "example", "of", "text", "justification."]

maxWidth = 16

Output:

[

"This is an",

"example of text",

"justification. "

]

Example 2:

Input:

words = ["What","must","be","acknowledgment","shall","be"]

maxWidth = 16

Output:

[

"What must be",

"acknowledgment ",

"shall be "

]

Explanation:Note that the last line is "shall be   " instead of "shall    be",

             because the last line must be left-justified instead of fully-justified.

             Note that the second line is also left-justified becase it contains only one word.

Example 3:

Input:

words = ["Science","is","what","we","understand","well","enough","to","explain",

        "to","a","computer.","Art","is","everything","else","we","do"]

maxWidth = 20

Output:

[

"Science is what we",

  "understand well",

"enough to explain to",

"a computer. Art is",

"everything else we",

"do "

]
