The Peak Power Hour

A power grid monitors 'surge' intervals from different sectors. Each surge is an interval [start, end] where the end is inclusive. You need to find the maximum number of sectors experiencing a surge at any single point in time. Input Format: The first line contains N, the number of surge intervals. The next N lines each contain two integers: start and end (inclusive). Output Format: Print the maximum number of overlapping surges. Example: Input: 3 1 5 2 6 5 8 Output: 3 (At time 5, all three surges overlap.)
