18. Recall that in a Round Robin CPU scheduling each process takes turn and runs for a specified time slice. Assume 3 processes are in ready states with required service times in seconds) as indicated in the following table. Assume also that allowed time slice is 10 seconds. What is the turn-around time for process P2? Process Service Time P1 25 P2 30 To a) 30 b) 55 c) 75 x d) 100 e) None of the above

21. Recall, a hash function, h, is a function that maps input of any size to output in some finite set. For example, in class we saw a hash function that takes as input any String and outputs a number between 0 and 25, according to the lexicographical ordering of the first letter of the String. What is a collision in the context of hashing? (A) When several keys are the same and entries get over-written. (B) When more than one key is hashed to the same output value. (C) When two different hash tables have the same name. (D) When a key is hashed to a value that is too large to fit in the array. (E) When a key is hashed and the output is the same as the input.

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
