In python language do thee following:

Some password scheme is designed such that the password must start with a special symbol in “$” “@” or “!” followed by four letters that could be in a..z followed by a similar special symbol followed by three letters in A..Z followed by a single digit. Write a program that takes from the user a string, and verifies whether the string abides by this password scheme. Do this once using regular expressions. Another time without using regular expressions.

1) Describe the performance impact of using the LIKE operation with a wild card character at the beginning of the value.

2) Under what circumstances is a non-matching index scan performed?

3) A query is written to access a single table. Furthermore, that query will return only a single row because an equality predicate is coded on the primary key for the table. A unique index exists to support the primary key. What type of access is likely to be the most efficient for that query?

4) How can stored procedures be used to optimize performance in a client/server application?

5) Under what circumstances will a table scan outperform indexed access?

Programming Language: C++

Create a base class called Shape which has 2 attributes: X and Y (positions on a Cartesian coordinate system). Since a shape is amorphous, set the class up so that an object of type Shape can not be instantiated.

Create three derived classes of your choice whose base class is Shape. These derived classes should have accessors/mutators for their class specific attributes, as well as methods to compute the area and the perimeter of the shape.

In main(), create a stack of pointers to Shape and push one object of each derived class onto the stack. Then, pop each shape pointer off of the stack and output that shape's area and perimeter, demonstrating polymorphism.

• Write a program that asks the user for a number in the range of 1 through 7. The program should display the corresponding day of the week, where 1 = Monday, 2 = Tuesday and so forth. If the user types in a 6 then "Saturday" should be printed on the screen.
• The program should display an error message if the user enters a number that is outside the range of 1 through 7.
• Name the source code file
• Test and run the program. Capture the output console and save it as an image file

Create a script that take a directory path from the user. What I want you to do is figure out the total size of all files in the directory. You will need to import the os module for this.

• dirs=os.listdir(DIRECTORY) where DIRECTORY is the direction you want to look at will return a list of all files in that directory.
• You can then use a for loop to go through dirs much like you went through a range in the previous examples you saw. Start by doing this and printing out the name of each file found.
• Once you have that working create a total variable and use os.path.getsize(FILE) where FILE is the file's size you want to add the file size to total.
• Print out the total size for all files in the directory. Note that the result is in bytes.
• Use an if statement to print the total out in KB if the total is over 1024. If it is not, simply print the total in bytes.
• Finally add to your program to also calculate the average size of a file in the given directory.

Develop a simple GUI-based Java program that may be used to control a lighting system

Develop code in a Scala Maven project to monitor a folder in HDFS in real time such that any new file in the folder will be processed .For each RDD in the stream, the following subtasks are performed concurrently: (a) Count the word frequency and save the output in HDFS. Note, for each word, make sure space (" "), comma (","), semicolon (";"), colon (":"), period ("."), apostrophe (“’”), quotation marks (“””), exclamation (“!”), question mark (“?”), and brackets ("[", “{”, “(”, “” ) are trimmed. (b) Filter out the short words (i.e., < 5 characters) and save the output in HDFS. (c) Count the co-occurrence of words in each RDD where the context is the same line; and save the output in HDFS.

(e) T F The set of all NP-hard problems is the same as the set of all NP-complete problems.

(f) T F The dynamic programming technique can be used to solve any optimization problem.

(g) T F If A ≤p B and A is NP-Complete, then B is also NP-Complete.

(h) T F If a problem is in P, then it can be solved in polynomial time nondeterministically

with brief explaination

VBA question, write a function check keyword in a string.

Question:

Function sentimentCalc(tweet As String) As Integer

This function should check each word in the tweet and if the word exists as one of the keywords in the positive list or negative list it should impact the overall sentiment value. The positive list and negative list words exist in the keywords sheet. Access the keywords as ranges within your VBA code. The case of the word is inconsequential. For instance, happy, HAPPY, or hApPy are all treated as positive words regardless of their case (Hint: StrComp).

We have a keyword excel show that which word is positive and which is negative. How to get the keyword please see the hit part below.

If the word is in the positive list, it should increase the sentiment value by 10, if it is in the negative list it should decrease it by 10.

For instance, if the positive list includes “happy”, “rally”, “growth” and the negative list includes “crash”, “scam”, “bad” then:

If the Tweet is “I am Happy that Bitcoin is showing growth.”. The sentiment value will be 10 + 10 = 20

If the Tweet is “I am happy that Bitcoin is a scam and will CRASH!” The sentiment value will be 10 – 10 – 10 = -10

You must remove the following punctuation characters from the tweet text in your VBA code before calculating the sentiment: ! . , ? : ) ( ;

You may do this using multiple lines each calling the Replace function or with an array, loop and one call to the Replace function. Both methods will be marked as correct.

HIT:

You will need to use the string functions StrCom p, Split and Replace In this function.To get the ranges from the keywords Sheet use Worksheet and Range object like so:

Dim positive As Range

Set positive = Worksheets("keywords").Range("A2:A76")

Dim negative As Range

Set negative = Worksheets("keywords").Range("B2:B76")

This will give you the range A2:A76.From the sheet namedkeywords As the variable named positive.You can do the same for the negative range (but with different cell references And variable names).

You will need to use nested loops. One to go through each word in the keywords and one to Go through each word in the tweet text.
