Postal bar codes. For faster sorting of letters, the United States Postal Service encourages companies that send large volumes of mail to use a bar code denoting the zip code (see Figure 7).
The encoding scheme for a five-digit zip code is shown in Figure 8. There are full-height frame bars on each side. The five encoded digits are followed by a check digit, which is computed as follows: Add up all digits, and choose the check digit to make the sum a multiple of 10. For example, the zip code 95014 has a sum of 19, so the check digit is 1 to make the sum equal to 20.
Figure 7 A Postal Bar Code
Figure 8 Encoding for Five-Digit Bar Codes
Each digit of the zip code, and the check digit, is encoded according to the table below, where 1 denotes a full bar and 0 a half bar:
The digit can be easily computed from the bar code using the column weights 7, 4, 2, 1, 0. For example, 01100 is 0 × 7 + 1 × 4 + 1 × 2 + 0 × 1 + 0 × 0 = 6. The only exception is 0, which would yield 11 according to the weight formula.
Write a program that asks the user for a zip code and prints the bar code. Use : for half bars, | for full bars. For example, 95014 becomes

- Discrete Mathematics: Assignment details: Replace all the 0 (Zero) digits in your ID by 4. Example: If your ID is 38104680, it becomes 38144684 Take the first 6 digits and substitute them in this expression (( A + B) / C) * ((D-E)/F)-2) according to the following table; Letter Replace by Digit Example Digit A 1st 3 B 2nd 8 C 3rd 1 D 4th 4 E 5th 4 F 6th 6 After substitution your expression will be similar to this (( 3 + 8) / 1) * ((4-4)/6)-2). Draw a rooted tree that represents your expression. What is the prefix form of this expression. 3.What is the value of the prefix expression obtained in step 2 above?arrow_forwardA palindrome is a word or phrase that is identical when you read from forward or backward, such as the words “racecar” and “madam.” A standard palindrome is similar to a perfect palindrome, except that spaces and punctuation are ignored in a standard palindrome. For example, “Madam, I’m Adam” is a standard palindrome because the characters are identical forward or backward, provided you remove the spaces and punctuation marks. Write a PHP script that checks words or phrases stored in two separate string variables to determine if they are a perfect palindrome. In addition, see if you can modify the program to check for standard palindromes. create a web page with a text field and “Reset” and “Submit” buttons. When a user clicks on the submit button, show the standard and perfect palindromes of the string that was entered in the text field on the same page.arrow_forwardConvert the decimal (base 10) number 40 to a binary (base 2) number that has only the digits '0' and '1'.

- The characters a to h have the set of frequencies based on the first 8 Fibonacci numbers as follows: a:1, b:1, c:2, d:3, e:5, f:8, g:13, h:21 A Huffman code is used to represent the characters. What is the sequence of characters, corresponding to the following code? 110111100111010arrow_forwardLeap Year: The earth doesn't take exactly 365 days to revolve around the sun and because of this we have leap years roughly every 4 years to make up the difference. The exact rule is: • Years divisible by 4 are leap years • except if they are also divisible by 100 and then they are not leap years (so 1900 was not a leap year), • unless they are also divisible by 400 and then they ARE leap years (so 2000 was a leap year). Part 1) Write a function in Python that takes as input a number, the year, and determines if it is a leap year or not. The function should return True if it is a leap year and False otherwise. Part 2) Write a main function to test out your leap year function on a few different illustrative inputs.arrow_forwardPerfect number, a positive integer that is equal to the sum of its proper divisors. The smallest perfect number is 6, which is the sum of 1, 2, and 3. Other perfect numbers are 28, 496, and 8,128. Write a code to check whether a entered number is a perfect number or not.arrow_forward
- 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…arrow_forward6. A palindrome is a number or text phrase that reads the same backwards or forwards. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a program that reads a 5 digit integer and determines whether it is a palindrome. Hint: One way to do this is to use division (/) and modulus (%) operators to separate the number into individual digits.arrow_forwardThe International Standard Book Number (ISBN) is a number that uniquely identifies a book.

- 6- You have two numbers ABCD and WXYZ (ex: 2345 and 7965). Write an algorithm using Pseudocode that decides whether ABCD is the inverse of WXYZ. (For example, if ABCD is 2356 and WXYZ is 6532 then the algorithm prints "Inverse" otherwise it will print "Not Invers")arrow_forwardA barcode scanner for Universal Product Codes (UPCS) verifies the 12-digit code scanned by comparing the code's largest digit (called a check digit) to its own computation of the check digit from the first 11 digits as follows: 1. Calculate the sum of the digits in the odd-numbered positions (the first, third,. eleventh digits) and multiply this sum by 3. 2. Calculate the sum of the digits in the even-numbered position (the second, fourth...tenth digits) and add this to the previous result. 3. If the last digit of the result from step 2 is 0, then 0 is the check digit. Otherwise, subtract the last digit from 10 to calculate the check digit. 4. If the check digit matches the final digit of the 12-digit UPC, the UPC is assumed correct By using C++ write a program that prompts the user to enter the 12 digits of a barcode separated by space. The program should store the digits in an integer array, calculate the check digit, and compare it to the final barcode digit. If the digits match,…arrow_forwardPerfect number, a positive integer that is equal to the sum of its proper divisors. The smallest perfect number is 6, which is the sum of 1, 2, and 3.
