Answers

Answer 1

Answer:

[tex](1100110)_2= 102_{10[/tex]

[tex](346)_7= 181_{10[/tex]

[tex](1024)_8 = 532_{10[/tex]

[tex](3B2)_{16} = 946_{10[/tex]

[tex](AF72)_{16}= 44914_{10[/tex]

[tex](120121)_3= 421_{10[/tex]

[tex](A22)_{11} = 1234_{10}[/tex]

Explanation:

Required

Convert to decimal

To do this we get the position of individual digits (starting from the rightmost digit).

Then each digit is multiplied by the base raise to power its position.

Lastly, we sum the results of the products.

Following the above steps, we have:

[tex]a.\ (1100110)_2[/tex]

[tex]= 1 * 2^6 + 1 * 2^5 + 0 * 2^4 + 0 * 2^3 + 1 * 2^2 + 1 * 2^1 + 0 * 2^0[/tex]

[tex]= 1 * 64 + 1 * 32 + 0 * 16 + 0 * 8 + 1 * 4 + 1 * 2 + 0 * 1[/tex]

[tex]= 64 + 32 + 0 + 0 + 4 + 2 + 0[/tex]

[tex]= 102[/tex]

Hence:

[tex](1100110)_2= 102_{10[/tex]

[tex]b.\ (346)_7[/tex]

[tex]= 3 * 7^2 + 4*7^1 + 6 * 7^0[/tex]

[tex]= 3 * 49 + 4*7 + 6 * 1[/tex]

[tex]= 147 + 28 + 6[/tex]

[tex]= 181[/tex]

Hence:

[tex](346)_7= 181_{10[/tex]

[tex]c.\ (1024)_8[/tex]

[tex]= 1 * 8^3 + 0 * 8^2 + 2 * 8^1 + 4 * 8^0[/tex]

[tex]= 1 * 512+ 0 * 64 + 2 * 8 + 4 * 1[/tex]

[tex]= 512+ 0 + 16 + 4[/tex]

[tex]= 532[/tex]

Hence:

[tex](1024)_8 = 532_{10[/tex]

[tex]d.\ (3B2)_{16[/tex]

[tex]= 3 * 16^2 + B * 16^1 + 2 * 16^0[/tex]

[tex]= 3 * 256 + B * 16 + 2 * 1[/tex]

B represents 11, so we have:

[tex]= 3 * 256 + 11 * 16 + 2 * 1[/tex]

[tex]= 768 + 176 + 2[/tex]

[tex]= 946[/tex]

Hence:

[tex](3B2)_{16} = 946_{10[/tex]

[tex]e.\ (AF72)_{16[/tex]

[tex]= A * 16^3 + F * 16^2 + 7 * 16^1 + 2 * 16^0[/tex]

[tex]= A * 4096 + F * 256 + 7 * 16 + 2 * 1[/tex]

A represents 10 and F, 15; So, we have:

[tex]= 10 * 4096 + 15 * 256 + 7 * 16 + 2 * 1[/tex]

[tex]= 40960 + 3840 + 112 + 2[/tex]

[tex]= 44914[/tex]

Hence:

[tex](AF72)_{16}= 44914_{10[/tex]

[tex]f.\ (120121)_3[/tex]

[tex]= 1 * 3^5 + 2*3^4 + 0*3^3 + 1*3^2 + 2*3^1 + 1*3^0[/tex]

[tex]= 1 * 243 + 2*81 + 0*27 + 1*9 + 2*3 + 1*1[/tex]

[tex]= 243 + 162 + 0 + 9 + 6 + 1[/tex]

[tex]= 421[/tex]

Hence:

[tex](120121)_3= 421_{10[/tex]

[tex]g.\ (A22)_{11[/tex]

[tex]= A * 11^2 + 2 * 11^1 + 2 * 11^0[/tex]

[tex]= A * 121 + 2 * 11 + 2 * 1[/tex]

A represents 10, so we have:

[tex]= 10 * 121 + 2 * 11 + 2 * 1[/tex]

[tex]= 1210 + 22+ 2[/tex]

[tex]= 1234[/tex]

Hence:

[tex](A22)_{11} = 1234_{10}[/tex]

Using range(1,101), make two list, one containing all even numbers and other containing all odd numbers. How can I do this on Python

Answers

Answer:

even = []

odd = []

for i in range(1,101):

if i % 2 == 0:

even.append(i)

else:

odd.append(i)

Using range(1,101), the list of even and odd number can be done in python as follows;

odd_numbers = []

even_numbers = []

for i in range(1, 101):

  if i%2 == 0:

     even_numbers.append(i)

  else:

     odd_numbers.append(i)

print(even_numbers)

print(odd_numbers)

The variable odd_numbers is initialise with an empty list

The variable even_numbers is initialise with an empty list.

Then we loop through the range 1 to 101 as required.

If the looped numbers is divided by 2 without a remainder then the number is appended to the empty list even_numbers.

Else if it has a remainder, the looped number are appended to the empty list, odd_numbers.

Then we print the even_numbers and odd_numbers.

In the Lesson Slides for this activity, we developed a method findChar for figuring out if a character was in a String.

The implementation was:

public boolean findChar(String string, String key)
{
for(int index = 0; index < string.length(); index++)
{
String character = string.substring(index,index+1);
if(character.equals(key))
{
return true;
}
}
return false;
}
However, there is a much more efficient and simple algorithm that we can use to determine if a character is in a String. Using the method signature public boolean findChar(String string, String key), figure out a more efficient method with a lower exection count.

Hint: We’ve learned a couple of methods that can tell us what index a character is at - can we use those to determine if the character is in a String?

Answers

public class JavaApplication78 {

   public boolean findChar(String string, String key){

       if (string.contains(key)){

           return true;

       }

      return false;

   }

   public static void main(String[] args) {

       JavaApplication78 java = new JavaApplication78();

       System.out.println(java.findChar("hello", "h"));

   }

   

}

First I created the findChar method using the contains method. It checks to see if a certain sequence of characters is in another string. We returned the result. In our main method, we had to create a new instance of our main class so we could call our findChar method.

A database has one physical schema and one conceptual (logical) schema but many external schemas (views).

Answers

Answer:

true

Explanation:

A database has one physical schema and one conceptual (logical) schema but many external schemas (views): a. True.

A database refers to a structured (organized) collection of data that are stored on a computer system and usually accessed in various ways such as electronically.

In database management, a database schema can be defined as a structure which is typically used to represent the logical design of the database. Thus, it denotes how data are stored (organized) and the relationships existing in a database management system (DBMS).

Generally, there are two (2) main types of a database schema and these include;

Physical database schema: it is only one per database.Conceptual (logical) schema: it is only one per database.

However, there are multiple number of external schemas (views) for each database because it is what an end user is interested in.

Determine the number of character comparisons made by the brute-force algorithm in searching for the pattern GANDHI in the text
THERE_IS_MORE_TO_LIFE_THAN_INCREASING_ITS_SPEED
(Assume that the length of the text-it is 47 characters long- is known before the search starts).

Answers

Answer:

Total number of character comparison = 43

Explanation:

Using the Brute force algorithm

The string of n characters is known as text, and the string of m characters is known as the pattern.

From the given information:

The text (n)=THERE_IS_MORE_TO_LIFE_THAN_INCREASING_ITS_SPEED

The pattern (m) = GANDHI

The total no of characters that we have in the text = 47

The total number of characters in pattern = 6

For a brute force algorithm;

Since; the first character of the pattern does not exist in the text, then the number of trials made can be attempted can be expressed as = n – m + 1

= 47 – 6 + 1

= 47 – 5

= 42

Thus; the algorithm will attempt the trial 42 times.

Now, for loop in the algorithm to run 42 times, the G in the pattern will have to align against the for T in the text, and in the last case, it will be aligned against the last space.

On each attempted trial, the algorithm will make one unsuccessful comparison.

However, at the trial at which the G in the pattern Is aligned with the G in the text, there will be two successful comparisons.

Hence, we can calculate the total number of character comparison as follows:

Total number of character comparison = [tex]\mathbf{\bigg ( ( 42 - (no. \ of \ failed \ comparison) ) \times 1 + (1 \times ( Two \ successful \ comparisons) ) \bigg ) }[/tex]

Total number of character comparison = ( (( 42 – 1) × 1 ) + ( 1 × 2) )

Total number of character comparison = 41 + 2

Total number of character comparison = 43

a) "Quit"
b) "q" only
c) "Q only
d) Either "q" or "Q"

Answers

Answer:

a) "Quit"  

c) "Q only

Explanation:

Given

String s = "Go";

while ((!s.equals("q"))&& (!s.equals("")))  {

System.out.println("In loop");

s = scnr.next();

}

Required

What input causes another execution

Analyzing the while condition

while ((!s.equals("q"))&& (!s.equals("")))  

This can be split into:

!s.equals("q")) && (!s.equals(""))

Meaning

When s is not equal to "q" and when s is not an empty string

In other words,

the loop will be executed when user input is not "q" and user input is not empty.

So, from the list of given options: The loop both will be executed when:

a) Input is "Quit"

c) Input is Q only

Input of q will terminate the loop, hence b and d are incorrect
