google bigquery - How to get pending cart users from Firebase analytics -


i have integrated firebase analytics data google bigquery , everyday new table gets created date stamp.

one sample table "projectid.com_dev_sambhav_android.app_events_20170821" 1 sample table shown below enter image description here

i have events add_items_to_cart, placed_order , cancelled_order. want query these bigquery tables see users have items in cart haven't placed order.

the problem: if user adds few items cart , places order, cart wont updated in firebase events. still shows items in cart.

example:

before placing order: cart items count 5 , placed order count 0

after placing order: cart items count 5 , placed order count 5

thats why not able pending cart information.

please advise

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
