Dart 언어를 접한 지 벌써 3년이 다 되어가는데 이런 요구사항이 있었던 적이 한 번도 없었어서 이제야 알게 됐다는 것이 놀라웠다. 그래서 오늘은 세 가지 Dart Map 구현체 HashMap, SplayTreeMap, LinkedHashMap에 대해서 살펴보고 각 구현체를 언제 사용해야 하는...Discuss·39 readsDart
Reshma Haridhasreshmaharidhas.hashnode.dev·Jan 16, 2024List in PythonList is a data structure similar to array. The List in Python can hold any number of elements in it. It does not have a fixed size. List is indexed. It means we can access the elements of a list by mentioning its index number. Indexing starts from 0,...DiscussPython
Wenqi Huangwenqi.hashnode.dev·Jan 8, 2024C# Data Structure - 3静态数组 Static Array 优点：通过索引就可以直接访问任意元素。 缺点：初始化时，就要知道元素数量。估大了空间浪费，估小了，空间不够用。 解决方案：动态数组 Dynamic Array，能自动调节空间大小，但依然不能充分利用全部空间。 进一步的解决方案：链表 Lined List，能充分利用空间，并实现灵活的动态内存管理。 链表 Lined List: 链表由一个个节点构成 每一个节点存储了两个信息，即： 实际存储的元素，和，下一个节点的引用（指针），用于将两个节...DiscussC#
