如何比较golang中的两个版本号字符串 [英] How to compare two version number strings in golang

问题描述

  a：=1.05 .00.0156
b：=1.0.221.9289
  

我想比较哪一个是大。如何在golang中做到这一点？

解决方案

将1.05.00.0156转换为0001+0005+0000+0156 int64。

$ b 将1.0.221.9289转换为0001+0000+0221+9289，然后转换为int64。
$ b

比较两个int64值。

试试 Go playground

I have two strings (they are actually version numbers and they could be any version numbers)

a := "1.05.00.0156"  
b := "1.0.221.9289"

I want to compare which one is bigger. How to do it in golang?

解决方案

Convert "1.05.00.0156" to "0001"+"0005"+"0000"+"0156", then to int64.

Convert "1.0.221.9289" to "0001"+"0000"+"0221"+"9289", then to int64.

Compare the two int64 values.

Try it on the Go playground
