"Even" Now by CodeChum Admin I'm really fond of even numbers, you know? That's why I'll be letting you make another even number problem yet again. This time, you need to print from a range of two inputted numbers, n1 and n2 (inclusive), all the even numbers from n2 down to n1, in descending order. Input 1. Value of n1 Description The first integer of the range Constraints The value of n1 is guaranteed to be lesser than or equal to n2. Sample 3 2. Value of n2 Description The second integer of the range Constraints The value of n2 is guaranteed to be greater than or equal to n1. Sample 10 Output The first line will contain a message prompt to input the value of n1. The second line will contain a message prompt to input the value of n2. The next line will contain all the even numbers from n2 down to n1. Enter · value · of · n1 : · 3Enter · value · of · n2 : · 1010 · 8 · 6 · 4
- Q: draw FA for the following regular Expression. 1. (0 + 1)*(010 + 0010)What is the explicit expression that represents how manyChallenge Problem (pyhton) T E S T S C O R E S Write a program that implements a test scores program. Valid test score entries are between 0 and 100 inclusive. The program should display a welcome message and run everything through the "main" function. have the ability to enter several test scores (try a loop) and print out the total score, as well as, the average score. continuously ask for test scores until the number 99.9 has been entered. test for valid entries and the value 99.9. If a test score is valid, the program should add the current score to the total score and update the number of test scores by one (+1), otherwise it displays an error message. Note : This assignment involves the use of a while loop and if-else decision making controls. You CANNOT use the reserved keywords break and continue for any portion of this program or any program for that matter throughout this course.
