- Create a postfix-to-infix translator with layers. The application should receive a postfix expression and output the corresponding infix expression until the user leaves. Throw an exception if the postfix phrase provided is illegal.Two friends are exchanging messages through regular post mail. They don’t want anyone to understand their messages in case anyone read them. The messages are in the form of an array of characters, where each character has a numeric value as illustrated in the below lookup table.A company wants to transmit data over the telephone, but it’s concerned that its phones may be tapped. All of its data is transmitted as four-digit integers. It has asked you to write a script that will encrypt its data so that the data may be transmitted more securely. Your script should read a four-digit integer entered by the user in a prompt dialog and encrypt it as follows: Replace each digit by (the sum of that digit plus 7) modulus 10. Then swap the first digit with the third, and swap the second digit with the fourth. Then output HTML5 text that displays the encrypted integer. In HTML and JavaScript

- you will create a spell checker. The program will take three command line arguments: number of words in the dictionary, a dictionary file name, and a text file name. The program will first create a hash table. The number buckets of the hash table should be about twice the number of words in the dictionary. Then, it will read the dictionary from the file, insert the words into the hash table, and report collision statistics. After reading the dictionary, the spelling checker will read a list of words from a text file. Each word will be looked up in the dictionary. If it is incorrect, it will be written to the standard output together with a list of suggested corrections. The algorithm for generating corrections is given below. Hash Table The hash table programs, QuadraticProbing.h and QuadraticProbing.cpp, are posted on Canvas. The programs use quadratic probing to deal with collisions. You should carefully study these programs and make some changes to collect the required statistics.…you will create a spell checker.
