Design a HashMap without using any built-in hash table libraries. Implement theMyHashMapclass: MyHashMap()initializes the object with an empty map. void put(int key, int value)inserts a(key, value)pair into the HashMap. If thekeyalready exists in the map, update the correspondingvalue. ...

Design a HashMap without using any built-in hash table libraries. To be specific, your design should include these functions: put(key, value): Insert a (key, value) pair into the HashMap. If the value already exists in the HashMap, update the value. get(key): Returns the value to w...

今天介绍的是LeetCode算法题中Easy级别的第167题(顺位题号是706)。在不使用任何内置哈希表库的情况下设计HashMap。具体而言,你的设计应包括以下功能: put(key,value):将一个(key,value)对插入HashMap。如果该值已存在于HashMap中,请更新该值。 get(key):返回指定键映射到的值,如果此映射不包含键的映射,则返...
要求不使用任何内置的hash table库设计一个HashMap。具体要求是:1)put函数能将一对(key, value)插入到HashMap,若已经有value,则进行更新;2)get函数能获得对应key的value,若不存在key,则返回-1;3)remove函数能在key存在的时候去除key以及key对应的value。可以将key和value分别设置为列表,put函数里对key的存在性先...
题目让我们设计一个 hashmap, 有put, get, remove 功能。 建立一个 int array, index 是key, 值是 value,具体看code。 Java Solution: Runtime: 76 ms, faster than 27.53% Memory Usage: 58.2 MB, less than 31.57% 完成日期:03/18/2019
