LeetCode ProblemDetermine if Two Events Have Conflict
You are given two arrays of strings that represent two inclusive events that happened on the same day, event1 and event2, where: Event times are valid 24 hours format in the form of HH:MM. A conflict happens when two events have some non-empty intersection (i.e., some moment is common to both events). Return true if there is a conflict between two events. Otherwise, return false.
