margin: 0px; font-weight: 700;">冲突解决</span>:由于哈希函数可能将不同的键映射到相同的索引,因此需要有一种冲突解决机制。在Go语言的映射实现中,当两个或多个键的哈希值相同时,它们会被链接到同一个桶的链表中。当查找一个键时,会遍历这个链表以找到匹配的键值对。</p></li><li><p><span style="box-sizing: border-box;

margin: 0px; font-weight: 700;">动态调整</span>:为了提高性能,映射的内部实现会根据需要动态调整哈希表的大小。当插入操作导致哈希表的负载因子超过一个阈值时,哈希表的大小会加倍,并且所有元素会被重新散列。这确保了映射在插入和查找操作上的时间复杂度接近于O(1)。</p></li></ol><p class="" style="box-sizing: border-box;
