A teacher wants a program to give extra points to students who fail a test. Write a Python program to do the following: (a) Ask

the user to enter 5 test scores. Store the scores in a list. Display the list. (b) Copy all 5 test scores to another list. Use a loop to examine each test score in the new list. If the score is below 60, add 10 extra points to the score. Display the list. (c) Compare the old score and new score of each student. If the old score and new score are different, display the two scores.

Answer:

Hi there! Please find the answer below.

Explanation:

The program below demonstrates how each of the requirements can be coded in a simple Python script. To copy the array, we can use the copy() method of the array. To calculate the diff, we can use a few different techniques, so I have implemented it using a loop over the arrays and just storing and displaying the difference in the 2 arrays.

new_string.py

def add_test_score(score):

 test_score.append(score);

contact_hash = {}

test_score = []

print("Enter 5 test scores: ");

for x in range(0, 5):

   input_string = input("Enter test score " + str(x + 1) + ": ")

   add_test_score(int(input_string));

print(test_score);

test_score_copy = test_score.copy();

for e in test_score_copy:

   if e < 60:

       test_score_copy[test_score_copy.index(e)] += 10;

diff = [];

for e in test_score:

   print(test_score[test_score.index(e)]);

   print(test_score_copy[test_score.index(e)]);

   if not test_score[test_score.index(e)] == test_score_copy[test_score.index(e)]:

       diff.append(e);

print(diff);

Write a loop that reads strings from standard input where the string is either "land", "air", or "water". The loop terminates wh
Setler79 [48]

The loop terminates when "xxxxx" is read in. If the word is land, the string followed by "land" get outputted. The same with air, and water.

Explanation:

int land = 0;

int air = 0;

int water = 0;

String word = "";

while(!(word.equals("xxxxx"))) {

word = stdin.next();

if(word.equals("land")) {

   land++;

}else if(word.equals("air")) {

   air++;

}else if(word.equals("water")) {

   water++;

}  

}

System.out.println("land:" + land);

System.out.println("air:" + air);

System.out.println("water:" + water);

2) [13 points] You’ve been hired by Banker Bisons to write a C++ console application that determines the number of months to rep
Paha777 [63]

Answer:

Check the explanation

Explanation:

CODE:

#include <iostream>

#include <iomanip>

using namespace std;

double getLoanAmount() { // functions as per asked in question

double loan;

while(true){ // while loop is used to re prompt

cout << "Enter the car loan amount ($2,500-7,500): ";

cin >> loan;

if (loan>=2500 && loan <= 7500){ // if the condition is fulfilled then

break; // break statement is use to come out of while loop

}

else{ // else error message is printed

cout << "Error: $"<< loan << " is an invalid loan amount." << endl;

}

}

return loan;

}

double getMonthlyPayment(){ // functions as per asked in question

double monthpay;

while(true){ // while loop is used to re prompt

cout << "Enter the monthly payment ($50-750): ";

cin >> monthpay;

if (monthpay>=50 && monthpay <= 750){ // if the condition is fulfilled then

break; // break statement is use to come out of while loop

}

else{ // else error message is printed

cout << "Error: $"<< monthpay << " is an invalid monthly payment." << endl;

}

}

return monthpay;

}

double getInterestRate(){ // functions as per asked in question

double rate;

while(true){ // while loop is used to re prompt

cout << "Enter the annual interest rate (1-6%): ";

cin >> rate;

if (rate>=1 && rate <= 6){ // if the condition is fulfilled then

break; // break statement is use to come out of while loop

}

else{ // else error message is printed

cout << "Error: "<< rate << "% is an invalid annual interest rate." << endl;

}

}

return rate;

}

int main() {

cout << setprecision(2) << fixed; // to print with 2 decimal places

int month = 0; // initializing month

// calling functions and storing the returned value

double balance= getLoanAmount();

double payment= getMonthlyPayment();

double rate= getInterestRate();

rate = rate /12 /100; // as per question

// printing as per required in question

cout << "Month Balance($) Payment($) Interest($) Principal($)"<< endl;

while(balance>0){ // while the balance is more than zero

month = month + 1; // counting Months

// calculations as per questions

double interest = balance * rate;

double principal = payment - interest;

balance = balance - principal;

// printing required info with proper spacing

cout <<" "<< month;

cout <<" "<< balance;

cout <<" "<< payment;

cout <<" "<< interest;

cout <<" "<< principal << endl;

}

cout << "Months to repay loan: " << month << endl; // displaying month

cout << "End of Banker Bisons";

Best case : 1.259

Bubble sort:

--------------------------------------------------------

Worst case : 1.990

Average case : 2.009.

Best case : 1.950

Explanation:

[NB: since it is very long there is the need for me to put it it a document form. Kindly check the doc. Files. The file A is the sort Analysis.Java file and the file B is the sort.Java file].

The concept of algorithm time measurement strictly depends on the following;

=> The measurement of time, space or energy on different sizes.

=> Plotting of the measurements and characterizing them.

=> Running or implementation of the algorithm.

Programming language such as Java can be used in accessing the operating system clock and Java had two static methods.
