Meeting Rooms II

intermediatelayer I10 · Intervals5 tests

Given intervals, an array of [start, end] meeting times, return the minimum number of rooms needed so that no two overlapping meetings share a room.

  • A meeting that ends exactly when another begins can reuse the same room
  • The input is not sorted
  • An empty schedule needs 0 rooms
  • A MinHeap class is already written for you in the starter — you only need the algorithm
