Clone graph Title Description: give you a reference to a node in an undirected connected graph. Please return a deep copy (clone) of the graph. Each node in the graph contains its value val (int) and a list of its neighbors (list[Node]). See LeetCode's official website for an example.

Week 269 race The topic is very simple. There are only three questions, and the fourth one is a little short. I'm still too good. I'll continue to work hard to train my thinking and speed. 5938. Find the target subscript after array sorting class Solution(object): def targetIndices(self, nums, target): """ :type nums ...

1. Problem solving ideas         Bucket sorting is one of the simplest sorting algorithms. Bucket sorting has many similarities and origins with counting sorting and cardinal sorting. The important thing of bucket sorting is its idea, not its specific implementation. For different elements to be sorted, the specific implem ...

1.Hash related When using HashMap, why can you find the corresponding value according to map.get(key) with time complexity O(1)? Because the physical structure uses a hash table Calculate the array position where the Entry should be stored according to a special algorithm. If the positions are the same, there are various methods to solve the ...

35. Search insertion position Given a sort array and a target value, find the target value in the array and return its index. If the target value does not exist in the array, returns the position where it will be inserted in order. You must use an algorithm with a time complexity of O(log n). Example 1: Input: num = [1,3,5,6], target = ...

📢 preface 🚀 Algorithm problem 🚀 🌲 Punching out an algorithm problem every day is not only a learning process, but also a sharing process 😜🌲 Tip: the problem-solving programming languages in this column are C# and Java🌲 To maintain a state of learning every day, let's work together to become the great God of algorithm ...

239. Maximum value of sliding window Give you an integer array nums, with a sliding window of size k moving from the leftmost side of the array to the rightmost side of the array. You can only see k numbers in the sliding window. The sliding window moves only one bit to the right at a time. Returns the maximum value in the sliding window. Ex ...
