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.

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.

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.

Esoterica " meant a secret book or method that was not known to the public. It usually contained unique and precious techniques or strategies that could help people gain an advantage or success in a specific field. However, the expression " secret to saving girls " lacked more context and was difficult to define. If taken literally, it might be a unique, unknown method or strategy to save girls. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The official photography software launched by Fast Hand was the Yitian camera app. It had a variety of features such as high-sweetness Japanese and Korean filter, vitality sticker, natural lightweight beauty, and so on. It could quickly take beautiful photos. The software also supported blurring the photo, so a simple smear could create a depth of field effect. At the same time, it provided Short videos and photos, which could be shared on third-party social media such as fast-hand, circle of friends, and Weibo. In addition, there was also the Kuaiying video editing app. Although its main function was video editing, it also integrated many beautiful filter effects to help users shoot Hollywood blockbuster videos. It also had a powerful intelligent voice recognition function that could automatically generate subtitles, and a massive music library that could be used to create customized and interesting original videos. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Different phones with different lenses had their own advantages when shooting pets. For example, the Oppo Find X6 Pro did not mention a specific lens, but it might have a function suitable for taking pets; the Pikfang pet photography robot had a telephoto and wide-angle lens, and its telephoto lens had a 3x zoom optical shot to make the picture more realistic. The Huawei P60 Pro uses a long-line sliding axis zoom lens group, which can flexibly control the focusing distance and achieve clear imaging from far to macro. Its telephoto macro has obvious advantages when shooting pets. It can take clear photos without disturbing the subject. The Oppo Reno10 Pro+ was equipped with a super-light periscope telephoto lens with 64 million pixels and a 1/2-inch large base. The pet picture was delicate and had good tolerance. It could capture the details of the fur, and the dark and bright parts retained enough details. The 3x optical zoom, the rare suspension prism anti-shake and fast focusing speed at the price of 3 - 4K made it have a high filming rate. The color processor could also restore the color of the pet's fur, nose and eyes. Therefore, if you use a mobile phone to shoot pets, you can consider a mobile phone with a telephoto lens (such as a sliding axis zoom lens group, a super-light periscope telephoto lens, etc.) to get better shooting results. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
