6.7 In Python, A palindrome is a word or a phrase that is the same when read both forward and backward. Examples are: "bob," "sees," or "never odd or even" (ignoring spaces). Write a program whose input is a word or phrase, and that outputs whether the input is a palindrome. Ex: If the input is: bob the output is: bob is a palindrome Ex: If the input is: bobby the output is: bobby is not a palindrome Hint: Start by removing spaces. Then check if a string is equivalent to it's reverse.
Q 3.I] Write a Java program to read the length and breadth using console and find the area of the rectangle. If the area is greater than 5oo then find the Perimeter of the rectangle. Area of rectangle=length∗breadth Perimeter of the rectangle=2∗(length breadth)
Q12,. A phrase is a palindrome if, after converting all uppercase letters into lowercase letters and removing all non-alphanumeric characters, it reads the same forward and backward. Alphanumeric characters include letters and numbers. Given a string s, return true if it is a palindrome, or false otherwise. Example 1: Input: s = "A man, a plan, a canal: Panama" Output: true Explanation: "amanaplanacanalpanama" is a palindrome. Example 2: Input: s = "race a car" Output: false Explanation: "raceacar" is not a palindrome..

Write a program that converts an ASCII text string from memory into all lowercase and stores the output to memory. The input string can contain uppercase and lowercase letters as well as spaces, punctuation (period, comma, question mark, exclamation point), and decimal digits. The input string will be null-terminated (that is, end with a 0 byte) and the output string is also to be null-terminated. (Observe: a 0 byte is different than the ASCII code for decimal digit 0 , which is 0x30.) Example: Convert the string "IN 2023, faLL stARTs on September 23." to "in 2023, fall starts on september 23.".
5.12.2: Switch statement to convert letters to Greek letters. Write a switch statement that checks origLetter. If 'a' or 'A', print "Alpha". If 'b' or 'B', print "Beta". For any other character, print "Unknown". Use fall-through as appropriate. End with newline. import java.util.Scanner; public class ConvertToGreek {public static void main (String [] args) {Scanner scnr = new Scanner(System.in);char origLetter; origLetter = scnr.next().charAt(0); /* Your solution goes here */ }}
Write an R program that reads the text file into a data frame. Using that data frame, print the mean, median, mode, average deviation, and standard deviation. Be sure to state which output is which, such as “The mean is: 25”. Write a Java program that reads the text file. Using meaningful print statements, output the mean, median, mode, and standard deviation. Write a Python program that reads the text file. Using NumPy and SciPy modules, print the mean, median, mode, and standard deviation. Write an R program that: Reads the text file. Using that data, create a two-dimensional array that is 2,500 rows by 100 columns. Also create a three-dimensional array that is 2500 by 10 by 10. Slice the two-dimensional array using a starting column index of 2 and an ending column index of 5. Print the results of the arrays and slice. Write a Java program that: Reads the text file. Using that data, create a two-dimensional array that is 2,500 rows by 100 columns. Slice the two-dimensional array…

5.23 In Python: Write a program with total change amount as an integer input that outputs the change using the fewest coins, one coin type per line. The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Ex: If the input is: 0 or less, the output is: no change Ex: If the input is: 45 the output is: 1 quarter 2 dimes Your program must define and call the following function. The function exact_change() should return num_dollars, num_quarters, num_dimes, num_nickels, and num_pennies.def exact_change(user_total)

1. Write a Python regex pattern that matches a valid email address, assuming that an email address consists of a username, followed by the "@" symbol, followed by a domain name, which in turn consists of one or more subdomains separated by dots, and ending with a top-level domain (e.g., .com, .org, .edu, etc.). 2. Using the re.findall() function in Python, write a Python code snippet that takes the text string and the regex pattern from Q4 and returns a list of all the email addresses found in the string. 3. Suppose you want to modify the regex pattern from Q4 to also match email addresses that contain hyphens ("-") in the username and/or domain name. What changes would you make to the pattern, and why? 4. Using the modified regex pattern from Q6, write a Python code snippet that takes the text string and the modified regex pattern, and returns a list of all the email addresses found in the string. Note: You can assume that the text string contains valid email addresses separated by…
