I had a front end phone interview with Amazon today. Just basic questions on how to come up with front end system design, and best practices. Like how to design a newspaper site. How to find errors. How to improve performance.

Coding question was:

/* Imagine we have a page that displays logs from our website in a table. Given these logs, write a function that tests whether a one URL
is linked to another URL, even if it take more than one link to get there. For example:

areURLsLinked("/", "/search") => true
areURLsLinked("/", "/reviews") => true
areURLsLinked("/", "/robots.txt") => false

URL Session ID Timestamp Referrer

/ C4CA4238A0B923820DCC509A6F75849B 1625153267 NULL

/ C4CA4238A0B923820DCC509A6F75849B 1625153254 /

/search C4CA4238A0B923820DCC509A6F75849B 1625153298 /

/detail C4CA4238A0B923820DCC509A6F75849B 1625153298 /search

/reviews C4CA4238A0B923820DCC509A6F75849B 1625153298 /detail

/robots.txt C81E728D9D4C2F636F067F89CC14862C 1625153340 NULL

*/

Whats the best way to get this? I used recursion and hash to keep track of previously accessed URL's so endless loops are avoided.

Thanks
