You are given a 2D integer array
logs where each
logs[i] = [birthi, deathi] indicates the birth and death years of the
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.
Input: logs = [[1993,1999],[2000,2010]] Output: 1993 Explanation: The maximum population is 1, and 1993 is the earliest year with this population.
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.
1 <= logs.length <= 100
1950 <= birthi < deathi <= 2050
