Explanation:

A Python program that finds the longest palindromic substring in a given string, considering special characters and spaces as part of the palindrome is given below.

Code:

def longest_palindrome(string):

   n = len(string)

   table = [[False] * n for _ in range(n)]

   # All substrings of length 1 are palindromes

   for i in range(n):

       table[i][i] = True

   start = 0

   max_length = 1

   # Check for substrings of length 2

   for i in range(n - 1):

       if string[i] == string[i + 1]:

           table[i][i + 1] = True

           start = i

           max_length = 2

   # Check for substrings of length greater than 2

   for length in range(3, n + 1):

       for i in range(n - length + 1):

           j = i + length - 1

           if string[i] == string[j] and table[i + 1][j - 1]:

               table[i][j] = True

               start = i

               max_length = length

   return string[start:start + max_length]

# Example usage

input_string = "babad!b"

result = longest_palindrome(input_string)

print(result)

This program defines the longest_palindrome function that takes an input string and uses a dynamic programming approach to find the longest palindromic substring within that string.

The program creates a 2D table to store whether a substring is a palindrome or not. It starts by marking all substrings of length 1 as palindromes and then checks for substrings of length 2.

Finally, it iterates over substrings of length greater than 2, updating the table accordingly.

The program keeps track of the start index and maximum length of the palindromic substring found so far.

After processing all substrings, it returns the longest palindromic substring using the start index and maximum length.

All the correct statements about data stored in databases include the following:

A. Code.org (and Applab) allow for both manual and code editing of databases.

C. Records can be complete duplicates of other records, including id numbers

D. Four main operations can be performed on the data, Create Read Update and Delete

E. Data is persistent across multiple runs of the program/app.

In a database management system (DBMS), a database can be defined as an organized and structured collection of data that are stored on a computer system as a backup and they're usually accessed electronically.

In this context, we can reasonably infer and logically deduce that data records can be created as complete duplicates of other data records, such as ID numbers. Additionally, CRUD (Create Read Update and Delete) is an abbreviation for the four main operations that can be performed on the data.

Question:

________ is NOT a reference type.

A. A class type

B. An interface type

C. An array type

D. A primitive type

Answer:

D. An primitive type

Explanation:

In many programming languages such as Java, types determine the capacity of a variable. Types, among other things, limit;

(i) the value that a variable can hold.

(ii) the values an expression can produce

(iii) operations supported on those values

(iv) determine the meaning of those operations.

Types are either primitive or reference.

(a) Primitive types can hold only a single value. Examples are:

byte, short, int, boolean, long, char, float, double.

(b) Reference types can hold more than a single value and support many complex functionalities that are not allowed in the primitive types such as inheritance, polymorphism e.t.c. Examples are:

class type, array type, interface type and even null type.

Therefore, the primitive type is definitely not a reference type.

All the options given belong to reference type EXCEPT: D. A primitive type.

To solve this recurrence relation, we can use the iterative method known as substitution method. First, we make a guess for the solution and then prove it by mathematical induction.

Let's guess that x(n) = log base 3 of n. We can verify this guess by induction:

Base Case: x(1) = log base 3 of 1 = 0 + 1 = 1. So, the guess holds for n = 1.

Induction Hypothesis: Assume that x(k) = log base 3 of k holds for all k < n.

Induction Step: We need to show that x(n) = log base 3 of n holds as well. We have:

x(n) = x(n/3) + 1

     = log base 3 of (n/3) + 1 (by induction hypothesis)

     = log base 3 of n - log base 3 of 3 + 1

     = log base 3 of n

So, x(n) = log base 3 of n holds for all n that are powers of 3.

Therefore, the solution to the recurrence relation x(n) = x(n/3) + 1 for n > 1, x(1) = 1, is x(n) = log base 3 of n for n = 3^k.

B. Manually deposit 10% of her paycheck in her savings account.

C. Pay all of her bills and then place the remaining money in her savings account.

D. Pay all of her bills and then place the remaining money in her piggy bank.

The correct answer to this question is A. Automatically reroute a portion of her paycheck to her savings account.

Explanation:

In this case, Velma needs to consistently save money for her vacation as this guarantees she will have the money for the trip. This means it is ideal every month she contributes consistently to her savings for the vacation.

This can be better be achieved by automatically rerouting a part of her paycheck for this purpose (Option A) because in this way, every month the money for the vacations will increase and the amount of money will be consistent, which means Velma will know beforehand the money she will have for the vacation. Moreover, options such as using a piggy bank or paying the bills and using the rest for her savings, do not guarantee she will contribute to the savings every month, or she will have the money she needs at the end.
