PREFIX SUM ARRAY: A prefix sum array is an array where each element at index i is the sum of all elements from the start (index 0) to index i of the original array.

Given an array containing both positive and negative numbers in random order. The task is to rearrange the array elements so that all negative numbers appear before all positive numbers.

Parallel computing continues to advance, addressing the demands of high-performance tasks such as deep learning, scientific simulations, and data-intensive computations. A fundamental operation within ...

Abstract: This paper presents a novel parallel prefix sum algorithm on n numbers by p processors. A parallel time analysis shows that this proposed algorithm is more efficient and easy-scalable than ...

Abstract: This paper presents a new efficient data structure, called “a BPA (Bitmap-Prefix-tree Array)” for discovering frequent closed itemset in large transaction database. Recently, most studies ...
