基于内容的变长分块(CDC)技术,能够用来对文件进行变长分块.而后用来进行反复性检測,广泛用于去重系统中.后来又出现了对相似数据块进行delta压缩,进一步节省存储开销. 所以就须要一种高效的相似性检測算法,在论文 WAN Optimized Replication of Backup Datasets Using Stream-Informed Delta Compression 提出的super-features 算法具有非常好的效果.主要思想是在滑动窗体进行分块的过程中,通过一个…
You have n super washing machines on a line. Initially, each washing machine has some dresses or is empty. For each move, you could choose any m (1 ≤ m ≤ n) washing machines, and pass one dress of each washing machine to one of its adjacent washing m…
Your task is to calculate ab mod 1337 where a is a positive integer and bis an extremely large positive integer given in the form of an array. Example 1: Input: a = 2, b = [3] Output: 8 Example 2: Input: a = 2, b = [1,0] Output: 1024 你的任务是计算 ab 对 133…
