# 前言
> 排序算法可能是你学编程第一个学习的算法，还记得冒泡吗？
当然，排序和查找两类算法是面试的热门选项。如果你是一个会写快排的程序猿，面试官在比较你和一个连快排都不会写的人的时候，会优先选择你的。那么，前端需要会排序吗？答案是毋庸置疑的，必须会。现在的前端对计算机基础要求越来越高了，如果连排序这些算法都不会，那么发展前景就有限了。本篇将会总结一下，在前端的一些排序算法。如果你喜…

## Background
We currently use `sort_by_key` to sort `PhaseItem`s in the sort phase, and `sort_unstable_by` to sort extracted sprites in `queue_sprites`.
* `sort_by_key` - _This sort is stable (i.…

Hello, I would like to know what is the appropriate way of matching patterns in Character columns.
In the vignettes it is clearly explained that Character columns should be preferred over Factor colu…

This issue is to discuss what functions should be ported from StatsBase to Statistics (#2). Some functions would better move to a separate package:
- statmodels.jl: should go to StatsAPI.jl

Hi,
I am working on a simulation and we started using GVDB to handle self collisions.
So far, we have got it working nicely, but I needed to make a bunch of modifications in the source and would l…

1.位运算
### 基础
|或运算：有1则为1
&与运算：两个为1才为1
~取反：0变1,1变0
**异或：相同的为0，不同的为1**。也可用“不进位加法”来理解。
异或操作的一些特点：
x ^ 0 = x
x ^ 1s(全1) = ~x
x ^ x = 0
c = a ^ b --> a ^ c = b , b ^ a = c //交换…
