https://leetcode.com/problems/maximum-number-of-events-that-can-be-attended

## Description

Given an array of `events` where `events[i] = [startDayi, endDayi]`. Every event `i` starts at `startDayi`and ends at `endDayi`.

You can attend an event `i` at any day `d` where `startTimei <= d <= endTimei`. Notice that you can only attend one event at any time `d`.

Return _the maximum number of event&#x73;_&#x79;ou can attend.
