Problem # Given an unsorted array of integers, find the length of the longest consecutive elements sequence. Solution # To solve the problem of finding the length of the longest consecutive elements sequence in an unsorted array of integers, we can use a hash set for efficient lookups. The algorithm involves iterating through the array and dynamically checking for consecutive sequences. Here’s how we can implement it in Python: ...
Problem # Given a list of intervals (each interval represented by a pair of integers), merge overlapping intervals and return the result in sorted order. Solution # The Python function merge_intervals successfully merges overlapping intervals and returns the result in sorted order. Here’s the code: def merge_intervals(intervals): """ Merge overlapping intervals and return the result in sorted order. :param intervals: A list of intervals, each represented as a pair of integers :return: A list of merged intervals in sorted order """ # Sort the intervals based on the starting value of each interval intervals. ...
