3262. Find Overlapping Shifts

Medium

Problem Explanation

Explanation:

To solve this problem, we can sort the shifts based on their start times. Then, we iterate through the sorted shifts and check for overlapping shifts. If the end time of the current shift is greater than the start time of the next shift, it indicates an overlap. We keep track of the maximum number of overlapping shifts at any given time.

Time Complexity: O(n log n) where n is the number of shifts
Space Complexity: O(1)

Solution Code

import java.util.*;

class Solution {
    public int findOverlappingShifts(int[][] shifts) {
        Arrays.sort(shifts, (a, b) -> a[0] - b[0]);
        
        int maxOverlapping = 0;
        int currentOverlapping = 0;
        
        for (int i = 0; i < shifts.length - 1; i++) {
            if (shifts[i][1] > shifts[i + 1][0]) {
                currentOverlapping++;
                maxOverlapping = Math.max(maxOverlapping, currentOverlapping);
            } else {
                currentOverlapping = 0;
            }
        }
        
        return maxOverlapping;
    }
}
