The task is focused around an AB test for optimization towards the hit rate (% of players who allow push notifications) and Player Retention.

You need to complete technical solutions coded in Python programming language and the solution description.

AB test

## Setup

Players (users) are randomly split in two groups:

- group1 - even loginIDs
- group2 - odd loginIDs

We are testing which is the best time / place to show popup to players asking them to allow push notifications:

- group1 - immediately after the installation (before the first tutorial battle)
- group2 - after the tutorial (which consists of 5 battles) We are optimizing towards:
- Hit rate (% of players who allow push notifications)
- Player Retention

Test was run for two weeks (14 days). Only players that participated in the test appear in the provided data.

## Data

There are two anonimized files:

- `notification_allowed.csv`
- `user_history.csv`

### notification_allowed.csv
Sent after request popup has been shown and player has answered (closing the app defaults to `false` as an answer).

```
login_id = int, starting from 1 time
allowed_notifications = true / false
date_id = int, starting from 0, measuring days since the start of the test
```

### user_history.csv
Generated at the end of each day. It is sent for every active user and for every payer (all time payer). When 21 days pass after the player has logged in for the last time, player no longer appears in this table. This is not true for payers, as they are eligible to appear in this table no matter how long has passed since the last log in.

```
