#Exercise 1

The first exercise deals with perfect, abundant, and deficient numbers; - A perfect number is one that is equal to the sum of its divisors - A abundant number is one that is greater than the sum of its divisors - A deficient number is one that is less than the sum of its divisors

The solution revolves around creating small functions that resolve part of the problem. My solution for finding a number's divisors revolve around finding the remainder after division of the number by all the numbers between 1 and the number divided by 2

The function categorize returns a python dictionary with the following keys:

perfectNumbers
abundantNumbers
defectiveNumbers

Example of categorize output in finding perfect, abundant, and defective numbers in between 1 and 20

{
  "abundantNumbers": [
    12,
    18,
    20
  ],
  "defectiveNumbers": [
    1,
    2,
    3,
    4,
    5,
    7,
    8,
    9,
    10,
    11,
    13,
    14,
    15,
    16,
    17,
    19
  ],
  "perfectNumbers": [
    6
  ]
}

Future Optimization:

The divisor function can be turned to return a generator which are more memory efficient than keeping the divisors in memory.

#Exercise 2

This challenge dealt with data visualization from three separate data sources. There is a cleaning phase for each of these data sources in order to standardize the data to view.

For the first source, the transformation needs to be the following:

{"d":1435708800000,"cat":"Cat 1","value":832.803815816826}

into

{"date": YYYY-MM-DD, "category": "CAT 1", "value": 832.803815816826}

For the third source, the transformation uses regular expressions in order to turn:

{"raw":"9OHbc9 O1 WHTxiBPa auwZIVD6 j8jMWWVH UdB6hy 20150618 XF 5xhcx15DD sbYFRPn dyoH1OOIF 6meHw pANknwa2h T imhs24gR5 #cat 1#","val":39.38690127513058}

into

{"date":"2015-06-18","category": "CAT 1", "val":39.38690127513058}

##Result:

Future Optimization:

Remove async: false option from Ajax calls as it is detrimental to performance.
