<p>Write a method to replace all spaces in a string with &#39;%20&#39;. You may assume that the string has sufficient space at the end to hold the additional characters,and that you are given the &quot;true&quot; length of the string. (Note: If implementing in Java,please use a character array so that you can perform this operation in place.)</p>
<p><strong>Example 1:</strong></p>
<pre>
<strong>Input: </strong>&quot;Mr John Smith &quot;, 13
<strong>Output: </strong>&quot;Mr%20John%20Smith&quot;
</pre>
<p><strong>Example 2:</strong></p>
<pre>
<strong>Input: </strong>&quot; &quot;, 5
<strong>Output: </strong>&quot;%20%20%20%20%20&quot;
</pre>
<p>&nbsp;</p>
