WebProgramming language and library implementations of scan may be either inclusive or exclusive. An inclusive scan includes input xi when computing output yi (i.e., ) while an exclusive scan does not (i.e., ). In the latter case, implementations either leave y0 undefined or accept a separate " x−1 " value with which to seed the scan. Webstd::exclusive_scan Computes an exclusive prefix sum operation using binary_op (or std::plus <>() for overloads (1-2)) for the range [first, last), using init as the initial value, and writes the results to the range beginning at d_first. "exclusive" means that the i-th input element is not included in the i-th sum. small cubby floating shelves https://groupe-visite.com
