Witryna10 sty 2024 · A sorting algorithm is said to be stable if two objects with equal keys appear in the same order in sorted output as they appear in the input data set. Formally stability may be defined as, how the algorithm treats equal elements. Let A [] be an array, and let ‘<‘ be a strict weak ordering on the elements of A [].
