Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

-scripting language Write a program that randomly generates a lottery between 100 and 999 (random.randint(100, 999)), prompts the user to enter a number in the same range, and determines whether the user wins according to the following rule: (1) If the user input matches the lottery in exact order, print "the award is $10,000". E.g., lottery = 123, input = 123(2) If the user input matches the lottery, but in wrong order, print "the award is $6,000". E.g., lottery = 123, input = 321(3) If two digits in the user input matches a digit in the lottery, print "the award is $3,000". E.g., lottery = 123, input = 612(4) If one digit in the user input matches a digit in the lottery, print "the award is $1,000". E.g., lottery = 123, input = 289(5) If none of the digits is matched, print "thank you".

You are given a string ternary_expr which represents a random nested ternary expression, you need to evaluate this expression, and report the result. Assumption can be as follows: ● ternary_expr only contains digits, ‘?’, ‘:’, ’T’, ‘F’ where ’T’ is true and ‘F’ is false. ● ternary_expr contains only one-digit numbers (i.e. in the range [0, 9]) The ternary expressions group right-to-left, and the result of the expression will always evaluate to either a digit, 'T' or 'F'. Requirements 1. Way of modeling the problem with the cost implications without using Stacks.

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. Complete the program to read the needed values from input, that the existing output statement(s) can use to output a short story.

A fish-finder is a device used by anglers to find fish in a lake. If the fish-finder finds a fish, it will sound an alarm. It uses depth readings to determine whether to sound an alarm. For our purposes, the fish-finder will decide that a fish is swimming past if:there are four consecutive depth readings which form a strictly increasing sequence (such as 3 4 7 9) (which we will call "Fish Rising"), orthere are four consecutive depth readings which form a strictly decreasing sequence (such as 9 6 5 2) (which we will call "Fish Diving"), orthere are four consecutive depth readings which are identical (which we will call "Constant Depth").All other readings will be considered random noise or debris, which we will call "No Fish."Create a Python program called "fishfinder_firstname_lastname" that takes 1 input of string of 4 numbers separated with comma. Your program must display "Fish Rising", "Fish Diving.", "Fish At Constant Depth" or "No Fish".Example:30,10,20,20 Must display No…
The International Standard Book Number (ISBN) is a number that uniquely identifies a book. Publishers can buy or receive ISBNs from the International ISBN Agency. There are two types of ISBNs: ISBN-13 and ISBN-10, which are 10- and 13-digits long, respectively.ISBN-10 has a pattern, where the last digit can be found using the first 9. Additionally, ISBN-10 can also be used to calculate its ISBN-13 equivalent (and vice versa). Write two functions in ISBN.java. The main method is implemented for you so you can test your functions. Instructions on how to run this file to make use of the test.txt file are detailed below. calculateISBN10(int[] isbn) computes the last digit of the ISBN-10 number. The first 9 of the 10 digits of the ISBN will be passed to the function as the parameter isbn integer array of size 10. The last integer in the array will be -1. Your job is to calculate the last digit (called the check digit), and update the last index of the isbn array with the computed…
A complex number is a number in the form a+bi, where a and b are real numbers and i is √(-1) The numbers a and b are known as the real part and imaginary part of the complex number, respectively. You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas: a + bi + c + di = (a+c) + (b+d)i (addition) a + bi − (c + di) = (a−c) + (b−d)i (subtraction) (a + bi) * (c + di) = (ac−bd) + (bc+ad)i (multiplication) (a + bi) / (c + di) = (ac+bd) / (c2+d2) + (bc−ad)i / (c2+d2) (division) You can obtain the Absolute Value for a complex number using the following formula: |a + bi| = √(a2 + b2) A Complex number can be interpreted as a point on a plane by identifying the (a,b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in the example below.
