Answer:

Informally, an algorithm is any well-defined computational procedure that takes some value, or set of values, as input and produces some value, or set of values, as output. An algorithm is thus a sequence of computational steps that transform the input into the output.

Write a Python 3 program to read from a .csv file containing rates from power companies. Your program should determine the avera

aliya0001 [1]

Answer:

In python:

file = open("rates.csv", "r")

ratecount = 0

ratesum = 0

mylist = []

rates = file.readlines()

for nums in rates:

num = nums.rstrip('\n')

mylist.append(int(num))

for i in num:

ratesum= ratesum + int(i)

ratecount = ratecount + 1

print("Maximum Rate: "+str(max(mylist)))

print("Minimum Rate: "+str(min(mylist)))

print("Average Rate: "+str(ratesum/ratecount))

Explanation:

This opens the csv file

file = open("rates.csv", "r")

This initializes the number of rates in the file

ratecount = 0

This initializes the sum of the rates

ratesum = 0

This initializes an empty list

mylist = []

This reads the rates into lines

rates = file.readlines()

This iterates through the rates (as a string)

for nums in rates:

This removes the newline character \n in the rates

num = nums.rstrip('\n')

This appends the rates (as an integer) to the empty list

mylist.append(int(num))

The following counts the rates in the file and also sum them up

for i in num:

ratesum= ratesum + int(i)

ratecount = ratecount + 1

This prints the maximum of the rates

print("Maximum Rate: "+str(max(mylist)))

This prints the minimum of the rates

print("Minimum Rate: "+str(min(mylist)))

This calculates and prints the average rate

print("Average Rate: "+str(ratesum/ratecount))

. Consider the problem of finding the largest element in a list of n elements. What will be the basic operation of an algorithm

natali 33 [55]

Answer:

Comparison.

Explanation:

When we have to find a largest in a list of n elements.First we have to iterate over the list so we can access all the elements of the list in one go.Then to find the largest element in the list we have to initialize a variable outside the loop with the minimum value possible and in the loop compare each element with this value,if the element is greater than the variable assign the element to the variable.Then the loop will find the largest element and it will be the variable.

Which method call converts the value in variable stringVariable to an integer?

zlopas [31]

Answer:

The correct answer for the given question is Integer.parseInt( string variable );

Explanation:

Integer.parseInt( string variable ); is the method in a java programming language that convert the string into the integer value. It takes a string variable and converted into the integer.

Following are the program in java which convert the string value into an integer value.

class Main

{

public static void main(String []args) // main function

{

String str1 = "10009";

// variable declaration

int k = Integer.parseInt(str1);

// convert the string into integer.

System.out.println("Converted into Int:" + k);

}

Output:

Converted into Int:10009

Convert.toInt( stringVariable );

Convert.parseInt( stringVariable,Integer.toInt( stringVariable ); are not any method to convert the string into integer .

Therefore the correct answer is :Integer.parseInt( stringVariable );
