1854 - Maximum Population Year.
Easy

You are given a 2D integer array logs where each logs[i] = [birth_i, death_i] indicates the birth and death years of the i^th person.

The population of some year x is the number of people alive during that year. The i^th person is counted in year x’s population if x is in the inclusive range [birth_i, death_i - 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 <= birth_i < death_i <= 2050
