Algorithms

Given a valid (IPv4) IP <code>address</code>, return a defanged version of that IP address.

A defanged&nbsp;IP address&nbsp;replaces every period <code>&quot;.&quot;</code> with <code>&quot;[.]&quot;</code>.

&nbsp;
Example 1:
<pre>Input: address = "1.1.1.1"
Output: "1[.]1[.]1[.]1"
</pre>Example 2:
<pre>Input: address = "255.100.50.0"
Output: "255[.]100[.]50[.]0"
</pre>
&nbsp;
Constraints:

<ul>
	<li>The given <code>address</code> is a valid IPv4 address.</li>
</ul>

Defanging an IP Address

String

给你一个有效的 <a href="https://baike.baidu.com/item/IPv4" target="_blank">IPv4</a> 地址&nbsp;<code>address</code>，返回这个 IP 地址的无效化版本。

所谓无效化&nbsp;IP 地址，其实就是用&nbsp;<code>&quot;[.]&quot;</code>&nbsp;代替了每个 <code>&quot;.&quot;</code>。

&nbsp;

示例 1：

<pre>输入：address = &quot;1.1.1.1&quot;
输出：&quot;1[.]1[.]1[.]1&quot;
</pre>

示例 2：

<pre>输入：address = &quot;255.100.50.0&quot;
输出：&quot;255[.]100[.]50[.]0&quot;
</pre>

&nbsp;

提示：

<ul>
	<li>给出的&nbsp;<code>address</code>&nbsp;是一个有效的 IPv4 地址</li>
</ul>
