WebExplanation: With findIndex the code tries to find the id in the given array. The callback function uses destructuring to let id be the property of the iterated object. When the callback function returns true, the findIndex iteration stops, and the corresponding index is assigned to i.If there was no match, i will be set to -1. If there was a match, splice will extract that … WebNow we can vectorize the improved algorithm, using numpy.searchsorted: import numpy as np def countlower4 (v, w): """Return the number of pairs i, j such that v [i] < w [j]. >>> countlower4 (np.arange (0, 20000, 2), np.arange (4000, 14000)) 45000000 """ return np.sum (np.searchsorted (np.sort (v), w)) And this is six times faster still:
