[LeetCode] intersecting linked list
subject Here are the head nodes headA and headB of the two single linked lists. Please find and return the starting node where the two single linked lists intersect. If two linked lists have no intersection, null is returned. As shown in the figure, two linked lists intersect at node c1: The tUTF-8...

malloc and free in C language
1, Why malloc in c language Malloc means memory allocate dynamically allocates memory. In order to make up for the shortcomings of static memory allocation, malloc has the following disadvantages: 1. For example, for a traditional one-dimensional array, such as int a[5], the length of the arrayUTF-8...

C language - Advanced pointer
We know the concept of pointer: A pointer is a variable used to store an address, which uniquely identifies a piece of memory space.The size of the pointer is fixed at 4 / 8 bytes (32-bit platform / 64 bit platform).Pointers are typed. The pointer type determines the ± integer step size of the UTF-8...

Data structure - sequence table
Sequence table Sequential table is a linear structure in which data elements are stored in sequence with a storage unit with continuous physical addresses. Generally, array storage is used. Complete the addition, deletion, query and modification of data on the array. The essence is array, but oUTF-8...

[initial level of data structure]: function realization of dynamic sequence table (realized in C language and analyzed with attached drawings)
1, Dynamic version sequence table Before implementing the sequence table, we should know that the sequence table can be divided into two versions according to whether it can be expanded or not, static version and dynamic version. The static version is to store the contents in the array. Once tUTF-8...
