Please i need a help in bash script (linux) ,if im allowed just to use nested ifs, i want to take numbers from user and each number will execute some statements; allowed inputs are 20,30,40. if the inputs entered were different then we should print a message "wrong number" and ask for entering again a number that is allowed. if the input is 20 then it will execute : echo "20989" if the input is 30 then it will execute3 : echo "90999" if the input is 40 then it will execute : echo "40909 "

a. Write a program named CheckMonth that prompts a user to enter a birth month. If the value entered is greater than 12 or less than 1, display an error message; otherwise, display the valid month with a message such as 3 is a valid month. b. Write a program named CheckM0nth2 that prompts a user to enter a birth month and day. Display an error message if the month is invalid (not I through 12) or the day is invalid for the month (for example, not between 1 and 31 for January or between I and 29 for February). If the month and day are valid, display them with a message.
python:def ohno_twozero(placeholder, statement): """ Question 1 - Regex You are typing a personal statement but accidentally used the number 0 instead of the letter o (the two are very close on the keyboard). After realizing this, seeing the mistake once does not bother you, but you absolutely cannot tolerate seeing it twice in a row. Therefore, you will need to replace any WORD where '00' shows up at any point with the given placeholder. Do not replace any NUMBER where 00 shows up. (e.g. '100' should stay as '100' and not be replaced with the placeholder). You may assume that when '00' shows up in a word, there will be at least one letter preceding it. Return the output string after making these changes. THIS MUST BE DONE IN ONE LINE. Args: placeholder (str) statement (str) Returns: str >>> ohno_twozero('epic', "I am n0w l00king at 500 t0tal h0urs 0n Super Smash Br0s.") "I am n0w epic at 500 t0tal h0urs 0n Super Smash…
Use C# (:Write an app that reads in a 5 digit number and determines if it is a palindrome. A palindrome is a number that reads the same backward as it does forward, for instance: 12321, 44444 or 22722. If the number inputted is not 5 digits long, display an error message and allow the user to input another number.

Java Instructions In this assignment, you will take one Infix expression as input and convert it to both Postfix expression, and Prefix expression Next, you will display the converted versions. See the example below. Finally, you will evaluate the expression, and print out the solution. See the example below. You can assume only integer numbers, +-*/ operators and parentheses are part of the input expression. However, the evaluated output should be of double type. The characters in the input and the output expressions will be separated by single spaces. See the example below. Please follow the same output pattern as shown below. Note: The test run below is just a sample. It does not imply that I will test your code with only this particular input. Make sure you thoroughly test your code before submitting it. Hints You can use Stacks for this task. You can take the input as a string by reading the line from the console. You only need to solve the problem for one input…

Print the source code after cleaning it as follows : 1. If there are comments you have to remove them all whether it's a single comment (e.g. : //) or a block comment (e.g.: /**/). 2. If there are any blank lines or lines consists of spaces you must remove them all. See the test cases carefully for more clarifications. Input Source code in C++ (maximum number of lines is 50).

Input a number (sequence number to be considered) from the console and calculate the Fibonacci series up tothat sequence and display the output on the screen. The code should check whether user types any negative number. If yes, it shows an error message andprompts again for input. Code should run without any error using SASM IDE. The code is able to calculate up to 25th Fibonacci number in the series. Consider the first two numbers are 0and 1. Required to use recursive function to calculate the final output number. For/ While loop to calculatethe Fibonacci series will not be considered. The result (only a number, do not need to show the series) should display on the screen, can use printf command or PRINT_DEC and PRINT_STRING command to show the output. The code should include adequate comments for the written assembly code.
You have been hired by the Department of Computer Science at Wayne State University to write a C++ console application to count the number of students who got a grade of "A- (90-92%)" and "B (83-86%)" in CSC 1101. Use a validation loop to get from the user the number of students in the section in the range 1-20. Then prompt the user for the point total for each of the students. Store the point totals in an integer array (declared of size 20). Then create and call two functions: stdGradeAminus() reads through the first n spots of the array and counts the number of point totals between 90-92. n is the number of students in the section. Here is part of the function declaration: int stdGradeAminus (int arr[], int n) { … } stdGradeB() reads through the first n spots of the array and counts the number those are between 83-86. n is the number of students in the section. Here is part of the function declaration: int stdGradeB (int arr[], int k) { … } Sample screenshot:…
