Answer:
C. <loc>
Explanation:
We need to mention the below details:
- location
- changed frequency
- last changed
- priority of page
We have the XML file for a sitemap, and we need to enter the above details for each of the Url. We need to enter the location, last changed, changed frequency and priority of the page for each of the URLs. And the URL of the home page is surrounded by the Loc tag. And hence, the correct option for this post is the C.<Loc> option.
You'll need a helper variable for this, so depending on your programming language, the solution becomes:
int helper;
helper = arr[i];
arr[i] = arr[j];
arr[j] = helper;
