Intervals Intersection (medium)
Problem Statement #
Given two lists of intervals, find the intersection of these two lists. Each list consists of disjoint intervals sorted on their start time.
Example 1:
Input: arr1=[[1, 3], [5, 6], [7, 9]], arr2=[[2, 3], [5, 7]]
Output: [2, 3], [5, 6], [7, 7]
Explanation: The output list contains the common intervals between the two lists.
Example 2:
Input: arr1=[[1, 3], [5, 7], [9, 12]], arr2=[[5, 10]]
Output: [5, 7], [9, 10]
Explanation: The output list contains the common intervals between the two lists.
