Since Hashtable is internally ordered (according to the hashcode of key), there are times when the use of Hashtable can result in an uncontrolled sequence of data, and there are two ways to solve the problem.Test code:DictionaryHt.

falls within the range of the array index. Copy Code code as follows: static int hash_str (char *key) { int hash = 0; char *cur = key; while (* (cur++)!= ' ") { hash + *cur; } return hash; } Use this macro to find the index of the key in the hash table #define HASH_INDEX (HT, key) (Hash_str ((key))% (HT)->size) This hashing algorithm is simpler,

The code is as follows: Static int hash_str (char * key){Int hash = 0;Char * cur = key;While (* (cur ++ )! = '\ 0 '){Hash + = * cur;}Return hash;}// Use this macro to obtain the index of the key in the hash table# Define HASH_INDEX (ht, key) (hash_str (key) % (ht)-> size) This hash algorithm is relatively simple and does not work well

Today, we share the 3D pre-defined model of the 3D series.The HT for WEB provides a variety of basic types for user modeling, unlike traditional 3D modeling, HT's modeling core is API-based interface, and is set up to build three-dimensional models with HT predefined primitive types and parametric interfaces. Let's talk about the predefined 3D models and parameter settings.HT pre-defined 3D models are: box,

Copy the Code code as follows:static int hash_str (char *key){int hash = 0;char *cur = key;while (* (cur++)! = ') ') {hash + = *cur;}return hash;}Use this macro to find the index of the key in the hash table#define HASH_INDEX (HT, key) (Hash_str (key))% (HT)->size) This hashing algorithm is relatively simple, its effect is not good, in the actual scenario will not use this hashing algorith

1. hashtable Overview Elements in the hashtable set exist as key/value. Key is used for quick search; value is used to store the value corresponding to the key. It is worth noting that both key and value are of the object type. Ii. hashtable operationsHashtable operations include: 1) Add a set Element2) retrieve collection Elements3) Traversal4) sorting set Elements5) modify the collection Element6) Delete collection Elements The following simple ConsoleProgramPerform the preceding ope

capacity, and the two memory modules must be completely consistent. The two-channel motherboard of SIS and via allows different capacities and types of memory to coexist, as long as there are two memory disks.(2) dual-channel memory control technology is widely used in common games and applications, with a very small gap with single-channel.(3) You need to purchase a motherboard that supports dual-channel memory control technology and two memory modules, which requires more costs.(4) The dual-c

1. Create hashtable Int zend_hash_init (hashtable * HT, // point to a hashtableuint nsize, // nsize indicates the maximum number of elements that the hashtable can possess. When we add new elements, this value determines whether to automatically increase based on the situation. This value is always the power of 2, if the value you give it is not in the form of a power of 2 //, it will be automatically adjusted to the power of its smallest 2. Its calc

Suddenly there is an idea, if you can put some of the different knowledge points on the same interface, and put in a box, so that I want to see what can be very direct display, and this box must be able to open. I use HT to realize my idea, code more than 100 lines, so little code can achieve this effect I think it is cattle.Let's take a look:The most basic of this example is the outermost box, so let's take a look at how to implement it:var New
