Problem description: there are now n ordered arrays in M groups, such as {1, 2, 3, 4}, {2, 3, 6}, {1, 3, 5, 7 }, select the data smaller than K in these arrays and return this value. Idea: Compare the minimum data selected each time by referring to the process of merging two Arrays 1. Define the selection position arra

Suppose rand5 can generate 1 ~ randomly ~ Use rand5 to generate rand7 () 1 ~ 7 (Equal Probability) 1. use rand5 to obtain rand2 (). When the number generated by rand5 is greater than 2, It loops until it generates 1 or 2 and the probability of generating 1 and 2 is

The Fibonacci Sequence, also known as the Golden series. In mathematics, the Fibonacci series are defined as follows by recursive Methods: F0 = 0, F1 = 1, Fn = F (n-1) + F (n-2) (n> = 2, in modern physics, quasi-crystal structure, chemistry, and other fields, the Fibonacci series are directly applied. Now, from an algorithm perspective, recursive and non-recursive methods are used for implementation:

: 1. to better understand and master XML, we recommend that you familiarize yourself with the syntax of HTML 4.0 and CSS 2.0. Master at least one of JavaScript and VBScript; programming experience, understanding of database theory and SQL can benefit everyone from learning XML. 2. tags in the XML document must appear in pairs. If it is an empty tag, it must end with a tag with the same name as "/", or use this 3. XML and the XSL document to be
