PHP implements Heap Sort and heap Algorithm introduction: Here I directly reference the beginning of "big talk Data Structure: As mentioned above, simply select sorting. It needs to be compared n-1 times to select the smallest record among the n records to be sorted. This can also be understood, it is normal that the first data needs to be compared so many times; otherwise, how can we know that it is the sm

Niuza kaibo has been around for nearly a year. Although it has been deserted for a long time, its construction work has been on the right track since last month, ensuring a certain update speed. Because cnblogs itself does not provide any traffic detection function (it is estimated that the server load is mainly taken into account), how many people visit me every day, it has always been an unclear thing. I didn't really want to solve this problem, but yesterday a talented girl, mm, accidentally

1. HadoopIt would is impossible to talk about open source data analytics without mentioning Hadoop. This Apache Foundation project have become nearly synonymous with big data, and it enables large-scale distributed processi Ng of extremely large data sets. A survey conducted by TDWI and SAS found this nearly percent of enterprises expected to has Hadoop clusters in product Ion by the end of 2016.However, it should be noted, the Hadoop on its own doesn

Heap sorting combines a bit of insertion sort and merge sort: It has a spatial complexity of O (1) and a time complexity of O (NLGN).To tell the heap sort, first of all the data structure "heap"Heap:A heap is a data structure that uses an array to hold a fully binary tree. Assuming the array name is a, the root node of

　　Google Analytics (analytics) divides all its reports into six categories: consoles, visitors, traffic sources, content, goals, and E-commerce . The console is the summary of the report summary. The goal is the website analyst in order to better analyze the website data and set the target for the website, can say the sales data, can also be the order quantity. Consoles and targets are not discussed here. T

There is no doubt that we have entered the era of Big Data (Bigdata). Human productive life produces a lot of data every day, and it produces more and more rapidly. According to IDC and EMC's joint survey, the total global data will reach 40ZB by 2020. In 2013, Gartner ranked big data as the top 10 trends in the future of information architecture. Gartner forecasts a cumulative output of $232 billion between 2011 and 2016.Big data has long existed, but there has been insufficient basic implement
