To gain experience of using and combing different sorting algorithms: election sort, insertion sort, merge sort, and quick sort.

ch4aika [34]

Answer:

Motivation? The search problem.

Sorting algorithms: insertion sort, shellsort, heapsort, mergesort, quicksort, bubblesort

At the very least, "general purpose" sorting algorithms require O(n log n) comparisons

Which decimal value (base 10) is equal to the binary number 1012?

GaryK [48]

Answer:

The decimal value of 101₂² base 2 = 25 base 10

Explanation:

The number 101₂² in decimal value is found as follows;

101₂ × 101₂ = 101₂ + 0₂ + 10100₂

We note that in 101 + 10100 the resultant 2 in the hundred position will have to be converted to a zero while carrying over 1 to the thousand position to give;

101₂ + 0₂ + 10100₂ = 11001₂

Therefore;

101₂² = 11001₂

We now convert the result of the square of the base 2 number, 101², which is 11001₂ to base 10 as follows;

Therefore converting 11001₂ to base 10 gives;

11001₂= 1 × 2⁴ + 1 × 2³ + 0 × 2² + 0 × 2 ¹ + 1 × 2⁰

Which gives;

16 + 8 + 0 + 0 + 1 = 25₁₀.

Write a function that implements another stack function, peek. Peek returns the value of the first element on the stack without

devlian [24]

Answer:

See explaination

Explanation:

StackExample.java

public class StackExample<T> {

private final static int DEFAULT_CAPACITY = 100;

private int top;

private T[] stack = (T[])(new Object[DEFAULT_CAPACITY]);

/**

* Returns a reference to the element at the top of this stack.

* The element is not removed from the stack.

* atreturn element on top of stack

* atthrows EmptyCollectionException if stack is empty

*/

public T peek() throws EmptyCollectionException

{

if (isEmpty())

throw new EmptyCollectionException("stack");

return stack[top-1];

}

/**

* Returns true if this stack is empty and false otherwise.

* atreturn true if this stack is empty

*/

public boolean isEmpty()

{

return top < 0;

}

}

//please replace "at" with the at symbol

Note:

peek() method will always pick the first element from stack. While calling peek() method when stack is empty then it will throw stack underflow error. Since peek() method will always look for first element ffrom stack there is no chance for overflow of stack. So overflow error checking is not required. In above program we handled underflow error in peek() method by checking whether stack is an empty or not.

You would like the user of a program to enter a customer’s last name. Write a statement thaUse the variables k, d, and s so that

mojhsa [17]

Answer:

1st question:

Use the variables k, d, and s so that they can read three different values from standard input an integer, a float, and a string respectively. On one line, print these variables in reverse order with exactly one space in between each. On a second line, print them in the original order with one space in between them.

Solution:

In Python:

k = input() #prompts user to input value of k i.e. integer value

d = input() #prompts user to input value of d i.e. float value

s = input() #prompts user to input value of s i.e. a string

print (s, d, k) #displays these variable values in reverse order

print (k, d, s)#displays these variable values in original order

In C++:

#include <iostream> // to use input output functions

using namespace std; //to identify objects like cin cout

int main() { //start of main function

int k; //declare int type variable to store an integer value

float d; // declare float type variable to store a float value

string s; // declare string type variable to store an integer value

cin >> k >> d >> s; //reads the value of k, d and s

cout << s << " " << d << " " << k << endl; //displays these variables values in reverse order

cout << k << " " << d << " " << s << endl; } // displays these variable values in original order

Explanation:

2nd question:

You would like the user of a program to enter a customer’s last name. Write a statement that asks user "Last Name:" and assigns input to a string variable called last_name.

Solution:

In Python:

last_name = input("Last Name:")

# input function is used to accept input from user and assign the input value to last_name variable

In C++:

string last_name; //declares a string type variable named last_name

cout<<"Last Name: "; // prompts user to enter last name by displaying this message Last Name:

cin>>last_name; // reads and assigns the input value to string variable last_name

The programs alongwith their outputs are attached.
