Mr. A really likes palindromes, so he is always looking for character strings that include palindromes. One day he realized that since pi is an infinite sequence, it might contain a lot of palindromes, and this inspired him to look for palindromes in large number sequences. As it is not possible to do so manually, he created a program to output the longest palindrome from an input sequence. The mission Build a program to output the longest palindrome from an input number. What is a palindrome? A palindrome is a sequence that reads the same backwards as forwards, e.g. madam, 1, 22, 1234321. You can check if a string A is a palindrome or not by using the pseudo code below. A == reverse(A) Implementation details CLI CLI Please implement a CLI application that takes the input value as an argument and outputs the result to standard output. For details, see the "CLI application template" section at the bottom of this page Input rules • The CLI application does not accept arguments. • A string consisting of numbers between 0 and 9 is given as standard input. • The length of the string is 1 million or less. Output rules • The longest palindrome from an input number is output. • If there are multiple longest palindromes available, the first one is output as the longest palindrome. 1/0 example $ ./[YOUR APP] < test/in/basic/basic_testcase01.txt

Problem Statement       The barcode used by the U.S. Postal System to route mail is defined as follows:  Each decimal digit in the ZIP code is encoded using a sequence of three half-height and two full-height bars.  The barcode starts and ends with a full-height bar (the guard rail) and includes a checksum digit (after the five-digit ZIP code or ZIP + 4), computed by summing up the original digits modulo 10.   Define the following functions:   Draw a half-height or full-height bar on stddraw. Given a digit, draw its sequence of bars. Compute the checksum digit.   Also define global code that read in a five- (or nine-) digit ZIP code as the command-line argument and draws the corresponding postal barcode.
