Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

本人自己平时总结的算法,如有不足,还请指点。欢迎参考。

1.数组小到大排序

soringn(arr)

(arr 为数组 例:arr=[2,3,4,1])

2.数组大到小排序

sorin(arr)

(arr 为数组 例:arr=[2,3,4,1])

3.整数反转

reversal(num)

(num 为整数 例:num=12345)

4.字符串中取数字

toNumber(string)

(string 为字符串 例:string="我是字符串 12345678")

5.两数之和

twoNum(nums,target)

例:输入:nums = [2,7,11,15], target = 9

输出:[0, 1]

(判断数组中那两个数相加等于 target,返回索引值)

6.回文数

reversalNum(num)

(判断一个数字是否是回文数 返回 true,false)

7.合并数组(小到大)

twoArray(arr1,arr2)

例:输入:l1 = [1,2,4], l2 = [1,3,4] 输出:[1,1,2,3,4,4]

(arr1,arr2 为数组,从小到大合并为一个数组)

8.删除数组重复项

repetition(arr)

例:输入: arr=[1,2,3,4,5,2,3,4,5]

输出:arrLen:5,newArr:[1,2,3,4,5]

9.搜索插入位置

insertion(nums,target)

例:输入:nums=[1,3,5,6] (排序数组) , target=5(目标值)

​ 输出:2(索引值)
