Ask if there is any performance difference between iframe and ajax on the partial switchover page. if so, is there a big gap? Which one has better performance? It has always been the development of a simple business layer. if the problem is too small, please bear with the ThinkPHP framework. if there is such a page, click the button to switch the content in the box, use ajax to request a specified page in the background (use smart to ask if there is a

Ultraviolet A 10829-L-gap substrings Question Link If a string is in the format of UGU and the length of G is l, the string is called L. If a string is given, ask the number of substrings of this string as G. Idea: poj1_3 was created before this question. One idea is to enumerate the length segments, so that for a U with the length of L, as long as the LCP is located forward and backward after the current position (L + G) respectively, the length of t

Tags: Water question Accumulation [Description]: enter a number. If this number is a prime number, 0 is output. If it is not a prime number, the difference between the two prime numbers closest to it is output, which is called prime gap. [Analysis]: This question is very dangerous, because I am a prime number table. Because the maximum prime number is 1299709, you must use long to create a table. Otherwise, the program cannot run. Pay attention to t

Overclocking for the love of DIY players, presumably are not unfamiliar. However, due to the skylake of the new generation of chipsets and the dual setting of FSB, the limit of overclocking is more elusive. Currently, the sixth Daicouri products that support overclocking only have i5-6600k and i7-6700k, so this time we take these two processor as the cut-in point, try to challenge the overclocking limit of the two products, at the same time compare i5 and i7 have what kind of overclocking potent

element of the bucket index out of bounds, we can define more than one Bukit. Once a bucket is defined, it can be placed in a bucket based on the size of the element. Note that Max Gap cannot exist between the elements of the same bucket, because the gap between the elements of the same bucket can only be bukitlength-1, if Max Gap is one of the two elements in t

What is the gap between Baidu and Google? The search engine needs to manage the captured results. When there are more and more index results, it is more and more difficult to ensure the storage and query speed and ensure the consistency of the content of tens of thousands of servers. Google published three papers around and described three technologies, GFS, BigTable, and MapReduce, to solve these problems. Google did not publish algorithm details, so
