Algorithm Analysis: 1316, obviously 1300 is a multiple of 13, but 16 is not a multiple of 11, you can think of any minus n 13 multiples from 1300 and the result is still a multiple of 13, so as long as 16 plus this minus n 13 is a multiple of 11, the two numbers are solved, and the answer may be more than one. But we

Extremeprogramming (XP) was proposed by kentbeck in 1996. Kentbeck worked with wardcunnheim in the early 1990s s to explore new software development methods, hoping to make software development easier and more effective. Kent carefully observed and analyzed the various prerequisites, possible actions, and difficulties for simplifying software development. In March 1996, Kent finally introduced a new idea of software development-XP in a project for DaimlerChrysler.XP
