Methods of StringBuilder class

The StringBuilder class can be used to create mutable strings. The methods defined in the StringBuilder class are widely used to manipulate and concatenate strings. It is a non-synchronized class which has public methods that can be accessed by multiple threads. It is not thread-safe.

Question

Problem Statement
Given five lists of characters (which are also known as strings), transform and concatenate the lists to form an encrypted
message such that:
• The first list of characters should be "rotated right 2", which means the last two characters in the string should be
moved to the front of the string. Example: "Hello" -> "loHel". (You can assume the string length will be at least 2.)
• The second list of characters should not contain the last two characters given. Example: "coding" --> "codi"
• The third list of characters should contain only the second half of the string. (You can assume the length of the string
is even.) Example: "CSC1101C" -> "101C".
• The fourth list of characters should swap the 3rd character with the 5th character. Example: "Robert" -> "Rorebt".
(You can assume the string length will be at least 5.)
• The last list of characters should contain the tags that enclose the entire message. For example, if the enclosure tag
provided is "<<>>", the entire concatenated message will be
<< loHelcodi101CRorebt >>. (Include a space before and after the encrypted message.) You can assume the length
of the tag is always four.
Lab I/O Format
For most programming assignments (both labs and assessments) this semester, a specific Lab Input/Output Format is
required. This format is described below:
• When prompting for input, use the prompt string WORD>, where WORD is a single, uppercase word which describes
the input. For example, this lab might choose: LIST1> and LIST2>.
• When providing output that will be graded, start the line with the word (OUTPUT followed by exactly one space, e.g.
OUTPUT. Think of this as "boxing your answer" on a math worksheet; it lets us quickly find your answer. Gradescope
will skip any output lines that do not start with OUTPUT
• You are welcome to have other output lines that do not begin with (OUTPUT); Gradescope will ignore these.
• A submission without exactly correct output formatting will receive an AUTOMATIC ZERO. This is because
Gradescope is automated-it does not look at your code, only the results, and thus the format of the results must be
consistent for all students.

Example Execution
Input the five lists of characters to be encrypted.
LIST1> Hello
LIST2> coding
LIST3> CSCI101C
LIST4> Robert
LIST5> <<>>
The encrypted message is:
OUTPUT << 1oHelcodi101CRorebt >>

Q4: Colouring Book IHaving spent the last couple of hours grading assignments, I decide it's time for a break. I take out my favourite colouring book, turn to a random page I haven't coloured in yet, and lay it on my desk. I then take out all my n crayons and line them up on the desk (it's a very long desk). The colour of the " erayon is a string c11 (eg. "alue"). Many of the crayons have the same colour. In fact, no matter how many crayons I have, there are at most 30 distinct colours amongst them. To start colouring, I always take a sublist (see Qi for a definition) of the crayons laid on the desk and put away the rest (too many options can be overwhelming and can lead to indecision).
