Topic:Given n cards and a random function, design a shuffle algorithmIdeas:Assuming that array A is the number represented by poker, the process of shuffling is the process of exchanging elements in the array.Shuffling is a random process and a combination of permutations.Assuming there are n cards, the possible arrangement of the combinations is n! =n* (N-1) *....*2*1.There are two kinds of random shuffle

Describe The Shuffle () method sorts all the elements of a sequence randomly. Grammar The following is the syntax for the Shuffle () method: Import Random random.shuffle (LST) Note: Shuffle () is not directly accessible, you need to import the random module, and then call the method by random static object. parameter LST-can be a sequence or tuple. return va

In the implementation of distributed system, shuffle is a very critical operation, which directly determines the feasibility of the algorithm executing in distributed environment. Shuffle is called data blending, and it is called exchange in some parallel systems. Shuffle the simplest way to do this is to make some sort of strategic segmentation of the data (such

the shuffle process in MapReduce is divided into two processes, map and reduce. Map End:1. (hash partitioner) after executing the map function, hash according to key, and the result of reduce the number of modulus (the key value pair will be processed by a reduce side) to get a partition number.2. (Sort combiner) writes the byte after the key-value pair and the partition number to the memory buffer (size 100M, loading factor 0.8), when the memory buff

Definition and usageThe shuffle () function rearranges the elements in the array in random order.Returns TRUE if successful, otherwise FALSE is returned.Note: This function assigns the new key name to the cells in the array. This will delete the original key name and not just reorder it.Note: since PHP 4.2.0, it is no longer necessary to sow the random number generator with the Srand () or Mt_srand () function, which is now automatically completed.

PHP has a very convenient to disrupt the array of functions shuffle (), this function in many cases will be used, but the JavaScript array does not have this method, it does not matter, you can expand A, do-it-yourself, well-clothed.

Shuffle () Definition and usageThe shuffle () function sorts the elements in the array in random order.If yes, TRUE is returned. Otherwise, FALSE is returned.Note: This function assigns a new key name to the cell in the array. This will delete the original key name, not just the reorder.Note: Since PHP 4.2.0, the random number generator is no longer needed to be planted using the srand () or mt_srand () fun
