Complete the following problem using concepts of STACK.
If you are using JAVA, you must include the main method as well which should test your other methods and print the outputs according to the tasks.
If you are using PYTHON, make sure your code has the methods invoked and proper printing statements according to the tasks.
Your program will take an arithmetic expression as a string input. For Example:
- “1+2*(3/4)”
- “1+2*[3*3+{4–5(6(7/8/9)+10)–11+(12*8)]+14”
- “1+2*[3*3+{4–5(6(7/8/9)+10)}–11+(12*8)/{13+13}]+14”
Program

Your program will determine whether the open brackets (the square brackets, curly braces, and the parentheses) are closed in the correct order.

Outputs:

Output 1

1+2*(3/4)

This expression is correct.

Output 2

1+2*[3*3+{4–5(6(7/8/9)+10)–11+(12*8)]+14

This expression is NOT correct.

Error at character # 10. ‘{‘- not closed.

Output 3

1+2*[3*3+{4–5(6(7/8/9)+10)}–11+(12*8)/{13+13}]+14

This expression is correct.

Output 4

1+2]*[3*3+{4–5(6(7/8/9)+10)–11+(12*8)]+14

This expression is NOT correct.

Error at character # 4. ‘]‘- not opened.

Task 1

Solve the above problem using an array-based stack.

Task 2

Solve the above problem using a linked list-based stack.

Objective: Take a sample feed, parse it, augment it, and output individual JSON objects for each product in it.

product.txt

The file contains several fields of basic product information for 1000 products.
Data for each product is on one line, with fields separated by a vertical pipe character.

This particular retailer classifies products into a particular store, department, category, and subcategory.

Example >

A Blender might have the following "taxonomy" or category classification.

Home & Garden > Kitchen & Dining > Appliances > Blenders

Store

Department

Category

Subcategory

store_id

department_id

category_id

subcategory_id

These IDs are also represented in a sort of shorthand.

They should all be prefixed by the first three letters of their respective field name.

A store_id of 1 becomes sto1

A department_id of 2 becomes dep2

A category_id of 3 becomes cat3

A subcategory_id of 4 becomes sub4

targets.txt

A system to keep track of these various classifications
- Example
  - A store_id of sto40 maps to a “target value” of 187298 in PromoteIQ's system

Output Example:

The desired output for the first product is one line of JSON that when pretty-printed looks like:

{

"sku": "22067130",

"name": "Brainboxes ES-571 Brainboxes Es-571 Industrial Isolated Ethernet to Serial + Switch - 1 x Network (R",

"description": "Brainboxes ES-571 Brand New Includes Lifetime Warranty Product # ES-571 Factory floors can be harsh environments.",

"priceList": 387.95,

"taxonomy": [

"sto2",

"dep7",

"cat270",

"sub18532"

"targetValues": [

187167,

187177,

187950,

196404

]

}

The taxonomy IDs have been mapped to their long form and placed in the taxonomy property.

Each taxonomy ID has also been mapped to its corresponding target value ID from the targets.txt file
- and that result is stored in the targetValues
- The priceList property is the product price as a JSON float, not a string

Question 6.6 MARKS] Two friends like to send messages to each other, but they don't want anyone else to read the messages. To keep the messages private, they change each letter in the original message to a different letter of the alphabet. For every letter, they both know which letter will be substituted for it, which is called an encoding. The message will contain only lowercase letters. It will not contain whitespace, digits, or punctuation. The receiver of a secret message doesn't want to convert it back to the original message by hand. Instead, that person asks you to write a function to do it. Following the function design recipe, define a function that given a secret message and the encoding used, returns the original message. Choose a meaningful function name, and add a docstring that includes the type contract, the description, and two examples that return different values. You must choose the types to use to represent the data, and you will be marked not only on the correctness of the function, but also on your choice of data structures.
