Domain Weight Calculation

You are given an array of strings domainScores. Each string has this format:

domain score

domain is a dot-separated domain name, and score is an integer weight assigned directly to that domain.

For every leaf domain, compute its total score. A domain is a leaf domain if it appears in domainScores and no other input domain has it as a suffix child.

The total score of a leaf domain is the sum of the scores assigned to that domain and all of its suffix ancestors that appear in the input.

For example, the suffix ancestors of mail.domain.com are domain.com and com.

Return one string for each leaf domain in lexicographic order. Each output string should have this format:

domain=totalScore

What the interview report shared

The interview report described a domain-score task: every domain has its own score, and the candidate had to output each leaf domain's accumulated score. The report included an example where mail.domain.com accumulated scores from mail.domain.com, domain.com, and com, and contact.user.test.com accumulated scores from all of its suffix ancestors. The report did not specify the function signature, constraints, or output ordering.

How FastPrep adapted it

FastPrep turned that report into a runnable practice problem by using an array of "domain score" strings as input and returning sorted "domain=score" strings. The lexicographic ordering rule and additional examples are practice scaffolding based on the reported task, not exact original wording.
