若key已经存在,就不会执行mappingFunction。返回oldValue newValue == null,不会替换旧值。返回null newValue != null,替换旧值。返回新值 代码语言:javascript 代码运行次数:0 运行 AI代码解释 public static void main(String[] args) { Map<String, Integer> map = new HashMap<>(); System.out.println...
这道题目,主要要学会使用一种哈希数据结构:unordered_set,这个数据结构可以解决很多类似的问题。 注意题目特意说明:「输出结果中的每个元素一定是唯一的,也就是说输出的结果的去重的, 同时可以不考虑输出结果的顺序」 这道题用暴力的解法时间复杂度是O(n^2),那来看看使用哈希法进一步优化。
