Insert Interval - LeetCode 57 - Python, JavaScript, Java, C++

Insert Interval LeetCode 57 with Python, JavaScript, Java and C++.

The Insert Interval problem, also known as LeetCode 57, focuses on inserting a new interval into a sorted list of non-overlapping intervals, while ensuring the list remains non-overlapping and sorted. Given a list of intervals and a new interval to insert, the goal is to merge any overlapping intervals that might result from this insertion.

To solve LeetCode 57, we iterate through the list, identifying intervals that either fall completely before, completely after, or overlap with the new interval. Intervals that fall outside the new interval can be directly added to the result. For overlapping intervals, we adjust the boundaries of the new interval to create a single merged interval. Finally, we append the merged interval to the result.

The Insert Interval problem is common in scheduling and event management, where adding new time slots needs careful adjustment to avoid conflicts. Understanding LeetCode 57 is key to mastering interval manipulation tasks.
