Answer:
Following are the solution to this question:
Explanation:
[tex]x^n[/tex] could be approximated by getting a small n loop as well as multiplying x for each incarnation in a linear time. It's very simple. Its key concept is to do it in log2n time.
[tex]x^n = x^{\frac{n}{2}}\ is \ obvious \ \ x^{\frac{n}{2}}[/tex]
Therefore,[tex]x^{n}, x^{\frac{n}{2}}[/tex] could be determined and divided by itself instead of [tex]x^n[/tex] calculation. It must be done frequently to ensure which half the research is done out with each stage.
Runtime:
Its repetition relationship of the above function is:
[tex]T(n) = T(\frac{n}{2}) + 1[/tex]
This can be resolved by master theorem, so it's obvious. The running time of this repeating ration, by master theorem, is [tex]O ( \log_2n )[/tex].
Pseudocode:
int exponent( int x_1, int y_1 )//defining a method exponent
{
if(y_1==1) //use if to check n value equal to 1
{return x_1;} //return x value
Int t= exponent(x_1,y_1/2);//call method
return t*t;//calculate square
}

PYTHONSorting TV Shows (dictionaries and lists)Write a program that first reads in the name of an input file and then reads the input file using the file.readlines() method. The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values (since multiple shows could have the same number of seasons).Sort the dictionary by key (least to greatest) and output the results to a file named output_keys.txt, separating multiple TV shows associated with the same key with a semicolon (;). Next, sort the dictionary by values (alphabetical order), and output the results to a file named output_titles.txt.Ex: If the input is:file1.txtand the contents of file1.txt are:20Gunsmoke30The Simpsons10Will & Grace14Dallas20Law & Order12Murder, She Wrotethe file output_keys.txt should contain:10: Will & Grace12: Murder, She Wrote14: Dallas20: Gunsmoke; Law & Order30: The Simpsonsand the file output_titles.txt should contain:DallasGunsmokeLaw & OrderMurder, She WroteThe SimpsonsWill & Grace
Answer:
with open("file1.txt", "r") as file:
lines = file.readlines()
mydict = dict()
for x in range(0, len(lines) - 1, 2):
mydict[lines[x]] = lines[x-1]
dict_keys = sorted(mydict.keys)
sorted_dict ={}
for key in dict_keys:
sorted_dict[key] = mydict[key]
with open("output_keys.txt", "a+") as writn:
for key, value in sorted_dict.items():
writn.write(key: value)
writn.write("\n")
dict_values = sorted(mydict.values)
with open("output_titles", "a+") as title:
for name in dict_values:
title.write(name)
title.write("\n")
Explanation:
The python program above reads in the file context, files.txt, and creates a dictionary of the file with the number of seasons as the key and movie title as the value. The sorted dictionary is saved in the output_keys.txt file and the titles in output_titles.txt file.

What is the practice of distributing responsibility among multiple people so that no one person has full control of
everything?
Separation of duties
Responsibility sharing
Separation of responsibility
None
Answer:
If the responsibilities are distributed ,the disputes amongst people wont take place because their wont be any partiality, everyone would be equal. Moreover it is difficult for one person to control everything at once and multiple people would help the work to be organized as everyone will have their own part of work which is supposed to be fulfilled.
Let us consider the easiest sorting algorithms – Maxsort. It works as follows: Find the largest key, say max, in the unsorted section of array (initially the whole array) and then interchange max with the element in the last position in the unsorted section. Now max is considered part of the sorted section consisting of larger keys at the end of the array. It is no longer in the unsorted section. Repeat this until the whole array is sorted. a) Write an algorithm for Maxsort assuming an array E contains n elements to be sorted, with indexes 0, 1,…,n-1. b) How many comparisons of keys does Maxsort do in the worst case and on average? Submit source code, test cases, results, and the answers to part (b)
Answer:
count = 0
for x in range(len(array)):
if count == Len(array) -1:
break
max = max(array[:-1 - count])
count += 1
if array.index(max) == -1:
break
else:
hold = array[-1]
array[-1] = max
array[array.index(max)] = hold
Explanation:
The python program is an implementation of a maxsort. The for loop iterates over the array, getting the maximum number for each reduced array and swaps it with the corresponding last items.

Write a C++ program to define an abstract class in polymorphism?
Answer:
Following are the program to this question:
#include <iostream>//header file
using namespace std;//namespace
class Val //defining abstract class
{
public://use access specifier
virtual int squ()=0;//declaring a method squ
void setval(int x) //defining a method setval
{
a=x;//holding value in a variable
}
protected://use access specifier
int a;//defining integer variable
};
class square: public Val //defining a class square that inherit abstract class
{
public://use access specifier
int squ() //defining squ method
{
return (a*a); //return square value
}
};
int main() //main method
{
square s;//creating class object
s.setval(5);//calling setval method
cout << "The square value is: " << s.squ() << endl;//print value by calling squ method
}
Output:
The square value is: 25
Explanation:
In the above code a two-class "Val and square" is declared, in which val is abstract class, in a method squ is declared, and setval is used to set the value.
In the next step, the square class inherits Val and defines the squ method, and uses the return keyword to return its calculated value.
In the main method square class object is created and set the setval value and call the squ method and print its value.

Write a program that reads 20 integers from the user into an array and uses a function arrayMinimum that accepts an integer array along with its size as parameters and returns the smallest element of the array. The program needs to output the result (the smallest array element).
Answer:
#include <iostream>
using namespace std;
int arrayMinimum(int myArray[], int myArraySize) {
int small = myArray[0];
for (int i = 0; i < myArraySize; i++) {
if(myArray[i]<small){
small = myArray[i];
}
}
return small;
}
int main(){
int myArray[20];
for(int i =0;i<20;i++){
cin>>myArray[i];
}
cout<<"The smallest is: "<<arrayMinimum (myArray,20);
return 0;
}
Explanation:
This solution is provided in c++
#include <iostream>
using namespace std;
This line defines the arrayMinimum function
int arrayMinimum(int myArray[], int myArraySize) {
This initializes the smallest of the array element to the first
int small = myArray[0];
This iterates through the array
for (int i = 0; i < myArraySize; i++) {
This if condition checks for the smallest
if(myArray[i]<small){
The smallest is assigned to the small variable
small = myArray[i];
}
}
This returns the smallest
return small;
}
The main method begins here
int main(){
This declares an array of 20 elements
int myArray[20];
The following iteration allows user input into the array
for(int i =0;i<20;i++){
cin>>myArray[i];
}
This calls the method and returns the minimum
cout<<"The smallest is: "<<arrayMinimum (myArray,20);
return 0;
}
