Project 2 in week 1-perform backtracking on the maze, and 2 in week 3- Problem:In the Maze problem, when looking for a path, the usual method is: Starting from the entrance, testing along a certain direction, if you can pass, continue to forward; if you cannot get through, return along the original path, and continue testing in another direction until all possible possibilities are tested. To ensure that t

Color Verification Code pictures can defend against other people's attack?Because when someone uses a polling technique to simulate a login, he doesn't know what your verification code is, can not get, because this is a picture, the computer does not recognize what the number is inside (unless you crack the verification code inside the interference, and then use the relevant image recognition technology may read out the verification code, here is not to pull this). Can not read the verification

Using the knowledge of permutation and combination, we can calculate that n bit can represent 2 ^ n cases, for example, 3 bit can represent 8 conditions:000 001 010 011 100 101 110 111Now we stipulate that in the n bits, if this bit is 1, then from right to left, how many BITs is this bit: Suppose it is t, then t is selected: for example: in 110, 3 and 2 are sele

If the UDP data is an odd byte, it is filled with a byte of 0. during calculation, the UDP pseudo-header will be added before the UDP header to check whether the data has arrived at the destination correctly twice. It is pseudo-header and byte filling:We ha

However, it is not easy to become a PHP programming expert. As many people think, as long as they can quickly write a few simple codes to solve a complicated problem, they are PHP programmers, real PHP experts also need to consider more other issues. The following three principles should be followed by a mature PHP programmer in programming. 1. Laziness is gold 2. write beautiful code 3. The pursuit of prog

The mechanisms to prevent competing states include semaphore (semaphore), spinlock (spin lock), completion (Completion volume), and atomic operations. The meaning of atomic operations: operations are inseparable. 1. What is concurrency? More than 1.1 execution units are executed simultaneously and concurrently. 1.2 Competition: 1.2.1 concurrent execution units accessing shared resources can easily lead to competition. 1.2.2 shared resources: hardware
