The language generated by the grammar in Figure 7.8 uses the terminal x to introduce the base. Amore common convention is to separate the base from the string of digits by some terminal symbol. Instead of x 8 4 3 1 to represent , a language following the common convention would use 8 x 4 3 1. (a) Design an LALR(1) grammar for such a language and specify the semantic actions that compute the string’s numeric value. In your solution,...
1 - Semantics - Attributes Grammar (25 points) Using the following grammar write an attributes grammar that can calculate the decimal value of an octal number. Grammar: number = list list = list octal octal octal = '0'|'1'|'2'|'3'|'4'|'5'|'6'|'7' Notes: An octal number consists of octal digits, i.e. O to 7. The following example shows how to convert the octal 67 to its equivalent decimal. The symbol star represents multiplication. 67 = 6*87 + 7* 8° = 6 * 8 +...
Please help me with the coding for LL(1)!! The given grammar was: P → PL | L L → N; | M; | C N → print E M → print "W" W → TW | ε C → if E {P} | if E {P} else {P} E → (EOE) | V (note: this has a variable O) O → + | - | * V → 0 | 1 | 2 | 3 (note: this has a terminal...

I have a python project that requires me to make a password saver. The major part of the code is already giving. I am having trouble executing option 2 and 3. Some guidance will be appreciated. Below is the code giving to me. import csv import sys #The password list - We start with it populated for testing purposes passwords = [["yahoo","XqffoZeo"],["google","CoIushujSetu"]] #The password file name to store the passwords to passwordFileName = "samplePasswordFile" #The encryption key for the caesar...
4) [15 points total (5 points each)] Assume you are given a sorted array A of n numbers, where A is indexed from 1 up to n, anda number num which we wish to insert into A, in the proper sorted position. The function Search finds the minimum index i such that num should be inserted into Ali]. It searches the array sequentially until it finds the location i. Another function MakeRoom moves A[i], .., AIn] to Ali+1]...AIn+1] same sort...

1.The following statement gets an element from position 4 in an array named myArray: x = myArray[4]; What is the equivalent operation using an array list named list.? A x = list.get(); B x = list.get(4); C x = list.get[4]; D x = list[4]; 2.Consider the following code snippet: ArrayList<Integer> num1 = new ArrayList<Integer>(); int data; Scanner in = new Scanner(System.in); for (int i = 0; i < 5; i++) { data = in.nextInt(); num1.add(data); if (data == 0 &&...
5.8 Sort Linked List Use mergersort to sort a linked list Do not use the following libraries: algorithm, cmath. Do not load the values into a vector and sort them. The sort must be done with a linked list Example Two lists 6->3->1->2->4->5 will return a list with 1->2->3->4->5->6. Input There will be no input read in anymore. Going forward use the hard-coded input on the template and ensure the program works. There will be one compare output test based...
