7.11 LAB: Print string in reverse Write a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending when the user enters "Done", "done", or "d" for the line of text. Ex: If the input is: Hello there Неy done then the output is: ereht olleH yeH

3.12 LAB: Seasons Write a program that takes a date as input and outputs the date's season. The input is a string to represent the month and an int to represent the day. Ex: If the input is: April 11 the output is: Spring In addition, check if the string and int are valid (an actual month and day). Ex: If the input is: Blue 65 the output is: Invalid The dates for each season are:Spring: March 20 - June 20Summer: June 21 - September 21Autumn: September 22 - December 20Winter: December 21 - March 19 247772.2002516.qx3zqy7
PP 6.4 Write a program that prints the first few verses of the traveling song “One Hundred Bottles of Beer." Use a loop such that each iteration prints one verse. Read the number of verses to print from the user. Validate the input. The following are the first two verses of the song: 100 bottles of beer on the wall 100 bottles of beer If one of those bottles should happen to fall 99 bottles of beer on the wall 99 bottles of beer on the wall 99 bottles of beer If one of those bottles should happen to fall 98 bottles of beer on the wall
3.4 LAB: Seasons Write a program that takes a date as input and outputs the date's season in the northern hemisphere. The input is a string to represent th month and an int to represent the day. Note: End with a newline. Ex: If the input is: April 11 the output is: Spring In addition, check if the string and int are valid (an actual month and day) Ex. If the input is Blue 65 the output is Invalid. The dates for each season in the northern hemisphere are: Spring: March 20-June 20 Summer June 21-September 21 Autumn September 22- December 20 Winter December 21- March 19
PYTHON 7.12 LAB: Warm up: Parsing strings (1) Prompt the user for a string that contains two strings separated by a comma. Examples of strings that can be accepted: Jill, Allen Jill , Allen Jill,Allen Ex: Enter input string: Jill, Allen (2) Report an error if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings.Ex: Enter input string: Jill Allen Error: No comma in string. Enter input string: Jill, Allen (3) Using string splitting, extract the two words from the input string and then remove any spaces. Output the two words.Ex: Enter input string: Jill, Allen First word: Jill Second word: Allen (4) Using a loop, extend the program to handle multiple lines of input. Continue until the user enters q to quit.Ex: Enter input string: Jill, Allen First word: Jill Second word: Allen Enter input string: Golden , Monkey First word: Golden Second word:…
5.22 LAB: Password modifier Many user-created passwords are simple and easy to guess. Write a program that takes a simple password and makes it stronger by replacing characters using the key below, and by appending "!" to the end of the input string. I need to figure out how to do this code using java. Thanks, Sarah Thomas
2.15 LAB: Musical note frequencies On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance (number of keys) from that key, and r is 2(1/12). Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print(f'{your_value1:.2f} {your_value2:.2f} {your_value3:.2f} {your_value4:.2f} {your_value5:.2f}')
0.O.9. Write a Java program to check if a given string is a palindrome or not. A palindrome is a word, phrase, number, or other sequence of characters that reads the same backward as forward, ignoring spaces, punctuation, and capitalization. For example, "racecar" and "Madam" are palindromes, while "hello" and "Java" are not. Your program should take a string as input and return true if it's a palindrome, and false otherwise.. Absolutely.
2.16 LAB: Musical note frequencies On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of fO * r^, where n is the distance (number of keys) from that key, and r is 20/12) Given an initial key frequency, output that frequency and the next 4 higher key frequencies.
4.17 LAB: Seasons Write a program that takes a date as input and outputs the date's season. The input is a string to represent the month and an int to represent the day. Ex: If the input is: April 11 the output is: Spring In addition, check if the string and int are valid (an actual month and day). Ex: If the input is: Blue 65 the output is: Invalid The dates for each season are:Spring: March 20 - June 20Summer: June 21 - September 21Autumn: September 22 - December 20Winter: December 21 - March 19 Use Python for this. Don't use other languages.
3.16 LAB: Mad Lib - loops Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways. Write a program that takes a string and an integer as input, and outputs a sentence using the input values as shown in the example below. The program repeats until the input string is quit and disregards the integer input that follows. Ex: If the input is: apples 5 зhоез 2 quit o the output is: Eating 5 apples a day keeps you happy and healthy. Eating 2 shoes a day keeps you happy and healthy. 2304021753326.gazgy7 LAB АCTIVITY 3.16.1: LAB: Mad Lib - loops main.cpp Load default template. 1 #include 2 #include 3 using namespace std; 5 int main( { 7 /* Type your code here. */ return e; 10 } 11
