1854. Maximum Population Year

https://leetcode.com/problems/maximum-population-year

Description

You are given a 2D integer array logs where each logs[i] = [birthi, deathi] indicates the birth and death years of the ith person.

The population of some year x is the number of people alive during that year. The ith person is counted in year x's population if x is in the inclusive range [birthi, deathi - 1]. Note that the person is not counted in the year that they die.

Return the earliest year with the maximum population.

Example 1:

**Input:** logs = [[1993,1999],[2000,2010]]
**Output:** 1993
**Explanation:** The maximum population is 1, and 1993 is the earliest year with this population.

Example 2:

**Input:** logs = [[1950,1961],[1960,1971],[1970,1981]]
**Output:** 1960
**Explanation:** 
The maximum population is 2, and it had happened in years 1960 and 1970.
The earlier year between them is 1960.

Constraints:

• 1 <= logs.length <= 100

• 1950 <= birthi < deathi <= 2050
