Have a HashMap<String, TreeMap<Integer, String>> hm to store keys. The value is TreeMap sorted based on timestamp. set, update hm. get, first get the TreeMap based on key, then use floorKey to find the largest key <= timestamp. Time Complexity: set, O(logn). get, O(logn). n...
A novel approach to generate house floor plans with semantic information is presented. The basis of this model is the squarified treemaps algorithm. Previously, this algorithm has been used to creat...

我想知道对于 HashMap 中的replace(Key, Value)方法,其时间复杂度是多少。 我的初步想法是它的时间复杂度为 O(1),因为获取值的时间复杂度为 O(1),而且我可以简单地替换与键相关联的值。 但我不确定是否应该考虑在使用 java.util 实现的大型 hashmap 中可能出现的冲突问题。 - a_confused_student 6 它的...
These fuel cells are of great interest because they can carry out, in a single operation, the processes of oxidation and refrigeration. This allows reduction of weight, volume, cost and complexity of the control system in the AC-PEFC. In this type of PEFC (and in general in any PEFC), ...
