Quick sort leetcode
Quicksort was an efficient sorting algorithm. The principle was to divide the records to be sorted into two independent parts by sorting. The keywords of one part of the records were smaller than the keywords of the other part of the records. Then, the two parts of the records were sorted separately to achieve the order of the entire sequence.
In terms of code implementation, there are the following sorting steps: first select the data of the left node as the pivot (reference value), start from the right, traverse the node data to the left (under the premise that the right > left condition is met), if the node data> pivot, continue to move to the left; If the node data <= pivot, assign the data of the current node to the left node, then stop the right traverse and start the left traverse. Starting from the left, traverse the node data to the right (under the premise that the left > right condition is met). If the node data < pivot, continue to move to the right; if the node data>= pivot, assign the current node data to the right node, then stop the left traverse and start the right traverse. When left and right overlap, the traverse ends, and the pivot is assigned to the coincidence node. The left side of the pivot node is the left array, and the right side is the right array. After that, the above steps were performed on the left array and the right array to complete the quick sorting.
In addition, the principle of quick sorting was also applicable when dealing with some related problems in Leetcode (such as the k-th smallest number and k-th largest number in the Leetcode topk problem). However, in different scenarios, it may be necessary to make appropriate adjustments according to the requirements of the question and the characteristics of the data structure. For example, when sorting the linked list, it may not be suitable to use the classic quick sort because the single-directional nature of the linked list is not good to traverse from the back to the front. If additional forward connections are added, additional space is needed.

Share your LeetCode success stories.
I had a LeetCode success story where I focused on understanding the problem - solving patterns. I noticed that many problems had similar underlying concepts. So, I made a list of common patterns like two - pointer, sliding window, and dynamic programming. I studied each pattern intensively, practiced related problems, and soon I could quickly identify which pattern to apply to a new problem. This approach really sped up my progress on LeetCode.

How did you achieve success on LeetCode?
For me, achieving success on LeetCode was about learning from others. I read a lot of solutions posted by top - rated users. Their code was often very clean and efficient. I studied how they used different data structures and algorithms. One time, I was stuck on a binary search problem. After looking at someone else's solution, I understood a better way to handle the boundary conditions. This way of learning from the community was really helpful.

The story of Tang Feng, the Immortal King of Flowers, was about the immortal emperor who had returned to the city after getting tired of his life of scheming.

How much is a one-day tour of Fenghuang Ancient Town?
The cost of a one-day trip to the Ancient Phoenix City varied from person to person. According to the more economical way of playing, the transportation cost was 15 yuan (Jishou to Fenghuang Ancient City), the accommodation was 30 yuan (Rainbow Bridge Youth Hostel), the city transportation was 14 yuan (shuttle bus was 7 yuan and 14 yuan for a round trip), the entrance ticket was 0 yuan, the food was 59 yuan, the clothes were rented for 50 yuan (makeup), and the other 70 yuan (20 yuan + 50 yuan for photos). In this way, the average person was 238 yuan. However, if you choose different modes of transportation, accommodation, food and beverage consumption, and entertainment, the cost may vary greatly. For example, someone spent 5032 yuan on a one-day trip to Fenghuang Ancient City. In addition, if the tour involved the core nine scenic spots of Fenghuang Ancient City, the ticket price was 128 yuan; the ticket price for the night tour of Tuojiang River was 80 yuan; the ticket price for the large-scale forest live performance in the border town varied from 130 - 580 yuan according to different regions; the ticket price for Qiliang Cave was 55 yuan, etc., all of which would increase the cost of the tour.
