Webvector dimensionality of d, the complexity of this algorithm is O(n2md) for immutable arrays. When using regular NumPy arrays, Tangent will intelligently handle index assignments and only copy the affected subarray onto the tape, bringing the complexity down to O(n2d+ndm). When a persistent array is used, the complexity goes down to O(ndm). Web30 jan. 2024 · 1) Initialize start and end indexes as start = 0, end = n-1. 2) In a loop, swap arr [start] with arr [end] and change start and end as follows : start = start +1, end = end – 1.
