How can I set the height of an outer div to always be equal to the height of a specific inner div?
I have an outer div that contains three inner divs. I want the leftmost inner div to always determine the height of the outer div. If the other inner divs have less content [than the leftmost div], they will have empty space. If they have more content [than the leftmost div], they will get a scrollbar. Some other questions on SO ask how to set the height of an outer div to the height of an inner div. However, in my case, I have multiple inner divs, and I don't know if the height of the outer div is greater or less than the height of the leftmost div. have what

Rewrite the title to: Vue 3: Transfer content to element and replace
I'm using Vue3's teleport to render an element into a div and it works as expected. Teleport will add the item to the selected element but will not replace the current element in the div. How can I set up the teleport to replace elements within the div, similar to how a vue app replaces the content of an anchor div when mounted? Background: For SEO reasons I need placeholder elements until the app renders and delivers.

哈希函数和哈希码

Course Introduction：典型的哈希函数首先将搜索键转换为称为哈希码的整数值，然后将哈希码压缩为哈希表的索引。Java的根类Object有hashCode方法，该方法返回整数哈希码。默认情况下，该方法返回对象的内存地址。hashCode方法的通用契约如下：每当重写equals方法时，都应该重写hashCode方法，以确保两个相等的对象返回相同的哈希码。在程序执行过程中，多次调用hashCode方法会返回相同的整数，前提是对象的数据没有改变。两个不相等的对象可能有相同的哈希码，但是你应该实现hashCode方法来避免太多这样的情况。

php中有哪些哈希函数

Course Introduction：PHP提供了以下哈希函数：md5()：生成128位哈希值，速度快但安全性低。sha1()：生成160位哈希值，安全性比md5()高但速度较慢。sha256()：生成256位哈希值，安全性较高、速度也较快。sha512()：生成512位哈希值，安全性最高但速度最慢。whirlpool()：生成512位哈希值，安全性与sha512()相当但速度较慢。ripemd128()：生成128位哈希值，安全性较高、速度也较

Golang asks for hash

Course Introduction：Hash is a function used to compress a message of any length into a fixed-length digest. In general, a hash function maps any input to a fixed-length string of outputs. Different inputs may map to the same output, which is called a Hash Collision. Hash functions are widely used in information security, data integrity checking and other fields. In this article, we will introduce how to use hash functions in Go language. There are many types of hash functions, each with its own unique

负载因子和重新哈希

Course Introduction：负载因子衡量哈希表的满度。如果超过加载因子，则增加哈希表大小并将条目重新加载到新的更大的哈希表中。这称为重新哈希。负载因子l(lambda)衡量哈希表的填充程度。是数量的比例元素与哈希表的大小，即l=n/N，其中n表示元素的数量，N表示哈希表中位置的数量。请注意，如果哈希表为空，则l为零。对于开放寻址方案，l介于0和1之间；如果哈希表已满，则l为1。对于单独的链接方案，l可以是任何值。随着l的增加，碰撞的概率也会增加。研究表明，对于开放寻址方案，您应该将负载因子保持在0.5以下，对于单独链接方案，您应该将
