Algorithms

Given two integers <code>left</code> and <code>right</code> that represent the range <code>[left, right]</code>, return the bitwise AND of all numbers in this range, inclusive.

&nbsp;
Example 1:

<pre>
Input: left = 5, right = 7
Output: 4
</pre>

Example 2:

<pre>
Input: left = 0, right = 0
Output: 0
</pre>

Example 3:

<pre>
Input: left = 1, right = 2147483647
Output: 0
</pre>

&nbsp;
Constraints:

<ul>
	<li><code>0 &lt;= left &lt;= right &lt;= 231 - 1</code></li>
</ul>

Bit Manipulation

给你两个整数 <code>left</code> 和 <code>right</code> ，表示区间 <code>[left, right]</code> ，返回此区间内所有数字 按位与 的结果（包含 <code>left</code> 、<code>right</code> 端点）。

 

示例 1：

<pre>
输入：left = 5, right = 7
输出：4
</pre>

示例 2：

<pre>
输入：left = 0, right = 0
输出：0
</pre>

示例 3：

<pre>
输入：left = 1, right = 2147483647
输出：0
</pre>

 

提示：

<ul>
	<li><code>0 <= left <= right <= 231 - 1</code></li>
</ul>
