In&nbsp;<em>HRML<\/em>, each element consists of a starting and ending tag, and there are attributes associated with each tag. Only starting tags can have attributes. We can call an attribute by referencing the tag, followed by a tilde, &#8216;<code>~<\/code>&#8216; and the name of the attribute. The tags may also be nested.<\/p>\n\n\n\n<p>The&nbsp;<em>opening tags<\/em>&nbsp;follow the format:<\/p>\n\n\n\n<p><code>&lt;tag-name attribute1-name = \"value1\" attribute2-name = \"value2\" ...&gt;<\/code><\/p>\n\n\n\n<p>The&nbsp;<em>closing tags<\/em>&nbsp;follow the format:<\/p>\n\n\n\n<p><code>&lt;\/tag-name&gt;<\/code><\/p>\n\n\n\n<p>The attributes are referenced as:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>tag1~value  \ntag1.tag2~name<\/code><\/pre>\n\n\n\n<p>Given the source code in HRML format consisting of&nbsp;<strong><em>N<\/em><\/strong>&nbsp;lines, answer&nbsp;<strong><em>Q<\/em><\/strong>&nbsp;queries.
