Implement the random generator of famous quotes Based on JQuery and AJAX, jqueryajax
This is a small application I made when I first got started with AJAX. The main functions are as follows:
1. click the button to randomly generate a famous saying and its author name. If there is no author name, "Unknown" is displayed ".2. click the button to share the famous saying on Twitter or Weibo.

1. Seeds and distribution
Five types of distributions are introduced here, including the following: (a), and (). Parameters required for distribution and use are provided.
2. Test the random number generator.
This section contains only one simple example, which is not described in detail. The following is the procedure for getting a random number from the example

Question :..... Take a long look. First, since the Lexicographic Order of the sorted sequence is the smallest, You must select as few numbers as possible. Then T is 1 ~ The M * n sequence does not exist. (At the beginning, I missed this condition) Okay, this question is greedy.Select the minimum point that is not marked each time, and mark both the lower left and the upper right corner (remember to mark the duplicate break, otherwise it will be down) Note that if two int values are opened fo
