A data structure is a specialized format for organizing, processing, retrieving and storing data. There are several basic and advanced types of data structures, all designed to arrange data to suit a specific purpose. Data structures make it easy for users to access and work with the data they...
“A data structure is a way of organizing data in some fashion so that later on, it can be accessed, queried, or even updated easily and quickly” It is a collection of values. The values can have relationships among them and they can have functions applied to them. Besides, each one ...
A heap, in the context of data structure, is a tree-based data structure that satisfies the heap property, where each element is assigned a key value, or weighting. The lower value key always has a parent node with a higher-value key. This is called a max-heap structure, and among al...
A general tree is a data structure with no constraints on the hierarchical structure. This means that a node can have any number of children. This tree is used to store hierarchical data, such as folder structures. Other common tree structures are: Binary tree:In a binary tree structure, a...
How do I query the allocated heap memory size and free heap memory size of an application? How do I obtain system logs when an application fault occurs? How do I use the hdc command to send a local file to a remote device? How do I check whether an application is a system appli...
How do I check whether an application is a system application? How do I capture the crash stack and implement the crash callback? How do I analyze the CPU usage of an application in running? How do I quickly read and analyze heap dump (memory), application memory usage, and maximum...
such as a whole data structure, several related data structures, or all memory reachable from a data structure. Sometimes a lock only protects part of a data structure (like the hash bucket chain of a hash table), but whatever the region is, it is critical that the programmer document it...
Time complexity is a measure of how fast a computer algorithm (a set of instructions) runs, depending on the size of the input data. In simpler words, time complexity describes how the execution time of an algorithm increases as the size of the input increases. ...
Buried deep in the System V Application Binary Interface document for the AMD64 Architecture, there is a footnote on page 24 that says, “%r10is used for passing a function’s static chain pointer.” What is a static chain pointer?
