Origami reaches the height of Mount Everest (for&while loop, closed function loop)
How many times do you fold a paper with a thickness of 0.1mm in half to reach a height of 8848180mm, the height of Mount Everest. (This note is suitable for coders who are familiar with loops and lists) [The details of learning are a joyful process] Python official website: python cutting edge. Unfortunately it’s […]

Level 8 Silver Challenge – Binary Tree Depth and Height Problems
104. The maximum depth of a binary tree – LeetCode Every function must run until return before it ends. + 1 directly at the return level means that the depth of the recursion at this level must be calculated. if you want if (root->left==nullptr & amp; & amp; root ->right == nullptr) { return 1; […]

vue el-dialog pop-up box custom instructions to implement drag and drop to change position-width-height
Foreword In actual development, we often use el-dialog pop-up boxes to make forms, which are usually centered. Part of the data is obscured When we want to view the data under the pop-up box, we can only close the pop-up box first, and then open the pop-up box after viewing the data. We can achieve […]
Canvas generates posters and dynamically calculates the size of the image to adapt to the height of the poster.

Height collapse problem in HTML and its solution
One: High degree of collapse Under normal circumstances, we do not set the height of the parent element, and let the child elements inside it automatically expand the height of the parent element, so that the height of the parent element can change with the change of the height of the child element. However, if […]
Data structure experiment – merge and find the root of the tree with a high height as the new root + find uses folding rules to implement the union and set experiment
Merge and find the root of the tree with the highest height when merging as the new root Experiment 1.1 Experimental content When the union search is merged, the root node of the tree with a higher height is used as the root node of the new tree to generate a new tree. After merging, […]
