A palindrome is a string that reads the same from left to right and from right to left. Design an algorithm to find the minimum number of characters required to make a given string to a palindrome if you are allowed to insert characters at any position
Answers
Answer:
Explanation:
The following code is written in Python. It is a recursive function that tests the first and last character of the word and keeps checking to see if each change would create the palindrome. Finally, printing out the minimum number needed to create the palindrome.
import sys
def numOfSwitches(word, start, end):
if (start > end):
return sys.maxsize
if (start == end):
return 0
if (start == end - 1):
if (word[start] == word[end]):
return 0
else:
return 1
if (word[start] == word[end]):
return numOfSwitches(word, start + 1, end - 1)
else:
return (min(numOfSwitches(word, start, end - 1),
numOfSwitches(word, start + 1, end)) + 1)
word = input("Enter a Word: ")
start = 0
end = len(word)-1
print("Number of switches required for palindrome: " + str(numOfSwitches(word, start, end)))

Write a program Ticket.py that will allow the user to enter actual speed
limit, the speed limit at which the offender was travelling, and the number
of previous tickets that person has received. The application should
calculate and display how many miles over the speed limit the offender
was travelling, the cost of the speeding ticket, and court cost. Use $10.00
as the amount to be charged for each mile per hour over the speed limit.
The court cost should be $50.00
Answers
Answer:
Following are the code to the given question:
def speedlimit():#defining a method speedlimit
a= int(input("Enter the offender's speed in mph: "))#defining a variable for input value
lim = int(input("Enter the speed limit in mph: "))#defining a variable for input value
n = int(input("The number of previous tickets that person has received: "))#defining a variable for input value
if (lim >= 20) and (lim < 70):#defining if block to check speed is between 20 to 70
if a > lim:#use if to check lim value greater than a
print("Driver was going", a-lim, "mph over the limit.")#print calculated value with message
print("The cost of the speeding ticket $",10*(a-lim))#print calculated value with message
else:
print( "Driver was going at a legal speed.")#print message
else:
print('Invalid speed limit.')#print calculated value with message
print("Court cost $",(50 + n*20))#print calculated value with message
speedlimit()
Output:
Please find the attached file.
Explanation:
In this code, a method "speedlimit" is declared that defines three variables that are "a, lim, and n" in which we input value from the user-end.
Inside the method, a nested conditional statement is used that checks the speed value is between 20 to 70 if it is true it will go to the next condition in which it checks lim value greater than a. It will use a print message that will print the calculated value with the message.

We're going to create a reservation making system to incorporate discounts for longer stays.
We’ll be getting the customer’s number of nights and we’ll also be getting the type of the room, which should be one of the following letters: D, Q, or K (for Double, Queen, or King). We’ll do that for two reservations.
To be able to advise the user on which reservation they should choose, we're going to have to make some calculations. First we'll need to determine the price per night. Double rooms go for $59.99 per night, Queen rooms are $69.99 per night, and King rooms are $79.99 per night.
Then we'll need to determine the discount. For every night over 2, a 15% discount should be applied. For example, if the stay is for 4 nights, then a 30% discount would be applied to the overall price.
Finally, we need to let the user know which stay is the cheapest or if they're the same cost.
Input:
The user should be prompted for a set of two values which represent the number of nights and the room type for the first reservation. The number of nights should be a whole number. The room type should be a single letter. The user should enter both values on one line, separated by spaces. The user should then be prompted for the remaining reservation.
Example (the highlighted part is what the program displays and the italicized part is the user input): Reservation 1 (#nights type): 3 D
The example executable:
An example executable is provided in this repository. You should be able to run it from your project folder. If you encounter a “permission denied” error when attempting to run the executable, type chmod u+x hotelsExecutable into the terminal and try running the executable again.
Requirements
main()
Functionality: The main function should prompt the user for two reservations. The room rate for each room for each reservation must be determined. Then the reservation total for each reservation can be calculated. A message should be displayed advising the user on which reservation is the better deal.
In addition to the main functions, your program should have 2 more functions:
getRoomRate()
Input Parameters: room type
Returned Output: room rate
Functionality: Given the type of room, this function should return the appropriate room rate.
calcReservation()
Input Parameters: room rate, number of nights
Returned Output: total reservation price
Functionality: Given the room rate and number of nights, this function should return the total reservation price with any applicable discount applied.

if a+1/a=3 find the valie of a^2+1/a^2
Answers
Answer:
a² + 1/a² = 7
Explanation:
a + 1/a = 3 ; obtain the value of a² + 1/a²
Taking a + 1/a = 3
Squaring both sides ;
(a + 1/a)² = 3²
(a + 1/a)(a + 1/a) = a² + a/a + a/a + 1/a² = 3²
(a + 1/a)(a + 1/a) = a² + 1 + 1 + 1/a² = 9
a² + 2 + 1/a² = 9
a² + 1/a² = 9 - 2
a² + 1/a² = 7
Hence,
a² + 1/a² = 7

Display all of the scores entered and the total score at the end. Using the code below, put the code in the proper order Sample output: Welcome to the Test Score Program Add score: 88.45 Do you want to continue
Answers
Answer and Explanation:
Using Javascript:
function AddScores(){
Window.alert("Welcome to the Test Score Program");
var ScoreList= new Array();
ScoreList.push(Prompt("Add Score"));
var WhatNext= Confirm("do you want to continue?");
If(WhatNext===true) {
do{
ScoreList.push(Prompt("Add Score"));
}
While(
Confirm("do you want to continue?")===true;);
}
Alert(ScoreList);
Alert(ScoreList.reduce(function(a,b){return a +b};,0);)
}
AddScores();
From the above code in javascript programming language, we have created a list ScoreList and added elements to it using push method of the array object and a do...while loop that checks the condition and then adds the user's input to the array. We then alerted the array to the screen and then summed up the array elements and also alerted to the screen.

What help in executing commands quickly

Answer:99
Explanation: Last summer, my family and I took a trip to Jamaica. My favorite part of the trip was when we went to a place called the Luminous Lagoon. We ate dinner and waited for the sun to go down. Then we boarded a boat and went out into the lagoon. That’s when the magic started.
At first we could not see very much in the darkness except for the stars in the sky. After a few minutes, however, I noticed some fish swimming in the water. They didn’t look like ordinary fish. These fish were glowing! Our guide explained that the glow came from tiny creatures in the water called dinoflagellates. These little animals are not visible to us, but their bodies produce light using something called bioluminescence, just like fireflies. There are so many of these creatures in Luminous Lagoon that the water around them seems to glow.
After our guide explained these facts to us, he told us to put our hands in the water. I was not sure if it would work, but I tried it. When I did, my hand looked like it belonged to a superhero! It was glowing bright blue. I hope someday I get to return to the Luminous Lagoon. The lights in the water were much more entertaining than the ones in the sky.
Problem:

The Greek prefix dinos- means “whirling” and the Latin root word flagellum means “whip”. What does dinoflagellate most likely mean as it is used in the passage?

Answer:
The function is as follows:
def kelvin_to_celsius(value_kelvin):
value_celsius = 0.0
value_celsius = value_kelvin - 273.15
return value_celsius
Explanation:
This defines the function
def kelvin_to_celsius(value_kelvin):
This initializes value_celsius to 0
value_celsius = 0.0
This calculates value_celsius
value_celsius = value_kelvin - 273.15
This returns the calculated value_celsius
return value_celsius
