Consider the following two data structures for storing several million words.
I. An array of words, not in any particular order
II. An array of words, sorted in alphabetical order
Which of the following statements most accurately describes the time needed for operations on these data structures?
A. Finding the first word in alphabetical order is faster in I than in II.
B. Inserting a word is faster in II than in I.
C. Finding a given word is faster in II than in I.
D. Finding the longest word is faster in II than in I.

Answer:

The correct answer is C.

Explanation:

Finding a given word requires the search operation. The search operation is faster in a sorted array compared to an unsorted array. In a sorted array the binary search method is used which runs on logarithmic time while in an unsorted array, there's no other way than linear search which takes O(n) time on the worst case where the required word is not in the array.

The statement which most accurately describes the time needed for operations on these data structures is: C. Finding a given word is faster in II than in I.

Binary search can be defined as an efficient algorithm that is designed and developed for searching an element (information) from a sorted list of data, especially by using the run-time complexity of Ο(log n)

Note: n is the total number of elements.

In Computer science, Binary search typically applies the principles of divide and conquer. Thus, to perform a binary search on an array, the array must first be sorted in an alphabetical or ascending order.

In conclusion, the statement which most accurately describes the time needed for operations on these data structures is that, finding a given word is faster in data structure II than in I.

# change amount as an integer input, and output the change using the fewest coins, one coin type per line. The coin types are Dollars, Quarters, Dimes, Nickels, and Pennies. Use singular and plural coin names as appropriate, like 1 Penny vs. 2 Pennies
my code produces no output and i cant find why?


coin_change =int(input())

def coin_change(cents):
if cents <= 0:
print( 'Zero cents.')
else:
quarter = cents // 25
dime = (cents % 25) //10
nickle = cents % 25 % 10 // 5
penny = cents % 5



print (coin_change )
# produces no output

You work for a small company that exports artisan chocolate. Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement.
You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds.
The conversions are as follows:
1 kilogram = 35.274 ounces
1 kilogram = 2.20462 pounds
1 pound = 0.453592 kilograms
1 pound = 16 ounces
1 ounce = 0.0283 kilograms
1 ounce = 0.0625 pounds
For the purposes of this activity the template for a function has been provided. You have not yet covered functions in the course, but they are a way of reusing code. Like a Python script, a function can have zero or more parameters. In the code window you will see three functions defined as def convert_kg(value):, def convert_pounds(value):, and def convert_ounces(value):. Each function will have a block showing you where to place your code.

Suppose Alice downloads a buggy browser that implements TLS incorrectly. The TLS specification says that, during the handshake, the browser should send a random 256-bit number RB. Instead of picking RB randomly the browser always sends all zeros. Describe an attack that is possible against this buggy browser and how to update the browser so that this attack is no longer feasible.

In order to implement the classic DoS flood attack, the attacker must generate a sufficiently large volume of packets to exceed the capacity of the link to the target organization. Consider an attack using ICMP echo request (ping) packets that are 500 bytes in size (ignoring framing overhead). How many of these packets per second must the attacker send to flood a target organization using a 0.5-Mbps link

Write a recursive method called sumTo that accepts an integer parameter n and returns a real number representing the sum of the first n reciprocals. In other words, sumTo(n) returns (1 1/2 1/3 1/4 ... 1/n). For example, sumTo(2) should return 1.5. The method should return 0.0 if it is passed the value 0 and throw an IllegalArgumentException if it is passed a value less than 0.

At the beginning of the semester, we studied partially filled arrays. This is when the number of elements stored may be less than the maximum number of elements allowed. There are two different ways to keep track of partially filled arrays: 1) use a variable for the numberElements or 2) use a sentinel (terminating} value at the end of elements (remember c-strings?). In the code below, please fill in the details for reading the values into the an array that uses a sentinel value of -1. Complete the showArray function as well.
#include
using namespace std;
void showArray(int array[]);
// ToDo: Code showArray function with one array parameter
int main()
{
const int MAX_SIZE=16;
int array[MAX_SIZE]; // store positive values, using -1 to end the values.
cout <<"Enter up to " << MAX_SIZE-1 << " positive whole numbers, use -1 to stop\n";
//To do: Read the int values and save them in the static array variable.
// When the user enters -1 or the array has no more room, leave the loop..
//To do: store -1 at the end of elements in the array
// Show array function
showArray(array);
return 0;
}
// To do: print out for the array
void showArray(int array[])
{
