Total the Audit Token Scores
Context
An archive system assigns an integer score to each token found in a document audit log. The scores may be positive, negative, or zero, and repeated scores remain separate entries. Return the combined score for the complete log, including the neutral result when no tokens were recorded.
Problem
Write a function that receives the integer scores from one document audit log and returns their total. Process the sequence from beginning to end, adding each score exactly once to a running total that starts at zero. Do not discard repeated values or treat zero as a special stopping signal. An empty log has total zero.
Examples
Example 1
Input:
scores = []Output:
0Explanation: The empty log returns 0, matching the required empty-sequence result.
Example 2
Input:
scores = [5, 0, -2, 5, 3]Output:
11Explanation: The log [5, 0, -2, 5, 3] returns 11 after including both 5 values and the zero.
Example 3
Input:
scores = [12, -7, 0, -7, 4, 12]Output:
14Explanation: The log [12, -7, 0, -7, 4, 12] returns 14 after including both 12 values and both -7 values.
Constraints
0 <= len(scores) <= 100000-1000000000 <= scores[i] <= 1000000000 for every i- Types:
scoresis int[]; result is int
Function signature
def sum_audit_scores(scores: list[int]) -> int
scoreslist[int]- The integer score attached to each token in the audit log, in log order.
- returns int
- The sum of all values in scores; returns 0 when the log contains no scores.

Notes
- The result must preserve the exact integer total.
