A comparator function is a custom function used in sorting algorithms to determine the order of elements based on specific criteria. By returning a negative, zero, or positive value, it dictates whether one element should appear before, after, or remain in the same position relative to another element in a collection.

The 'Order of Elements' refers to the specific sequence in which elements are arranged or appear, which can significantly affect the properties and outcomes in various contexts, such as chemistry, mathematics, and computer science. Understanding this order is crucial for predicting behaviors, optimizing processes, and ensuring accurate results in scientific and technical applications.
