A programming problem requiring manipulation of data structures and implementation of an algorithm to achieve the desired output.
AI-Expanded — inferred from the question title, not from the original candidate report
Given a collection of unsorted integer intervals, design an algorithm to merge all overlapping intervals into a single set of non-overlapping ranges. Your solution should utilize an efficient sorting strategy and a stack-based data structure to track the merged intervals, ensuring an optimal time complexity of O(n log n).
