# 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`
