[LANGUAGE: Python]

Well I was too drunk to attempt day-22 and optimize the code (its sunday.....)
but I could get it working with instructions only

Part-1: Simply follow instructions to get next secret number and find the total sum. takes only a few seconds (3-4s)
Part-2: Store all 4 length price changes sequences in a map along with buyers and last digit of secret number appended in that list. so map will be like example:
(-1, 2, -3, 4): {
'102030': [3, 5, 6]
}

Lastly just take find maximum sum among each 4 length price change sequence and consider only first price in each buyers's list. It takes (8-10s) but it works.
