Job Log Analyzer

Problem Context

In mainframe environments, SDSF (System Display and Search Facility) is a critical tool used to monitor, manage, and analyze job output. Jobs submitted to z/OS produce output logs (called SYSOUT or job logs) that contain return codes, messages, and step-level results. Your task is to simulate a simplified SDSF-style log analyzer.

You are given a list of job log entries. Each entry is a string in the format:

<JOBNAME> <STEP> <RC> <MESSAGE>

• JOBNAME — alphanumeric job name (up to 8 chars)
• STEP — step name within the job
• RC — return code (integer, 0 = success, 4 = warning, 8+ = error)
• MESSAGE — a description string (no spaces)

Your goal is to parse the job log entries and return a summary of each unique job, reporting:

1. The highest return code encountered across all steps.
2. The total number of steps executed.
3. The job status: "SUCCESS" if max RC == 0, "WARNING" if max RC == 4, "FAILED" if max RC >= 8.

Return the results as a list of strings, one per unique job, sorted alphabetically by job name, in the format:

<JOBNAME>: STEPS=<count>, MAXRC=<rc>, STATUS=<status>

Input Format

• logs: A list of strings, each representing one log entry.

Output Format

• A list of strings, one per unique job, sorted alphabetically by job name.

Examples

Example 1

Input: ["JOBABC STEP1 0 OK", "JOBABC STEP2 4 WARN", "JOBABC STEP3 0 OK"] Output: ["JOBABC: STEPS=3, MAXRC=4, STATUS=WARNING"] Explanation: JOBABC has 3 steps. The highest RC is 4, so status is WARNING.

Example 2

Input: ["JOBX STEP1 0 OK", "JOBY STEP1 8 ERROR", "JOBX STEP2 0 DONE"] Output: ["JOBX: STEPS=2, MAXRC=0, STATUS=SUCCESS", "JOBY: STEPS=1, MAXRC=8, STATUS=FAILED"] Explanation: Two distinct jobs. JOBX succeeds; JOBY fails with RC=8.

Example 3

Input: ["PAYJOB STEP1 12 ABEND", "PAYJOB STEP2 0 OK"] Output: ["PAYJOB: STEPS=2, MAXRC=12, STATUS=FAILED"] Explanation: RC=12 is >= 8, so status is FAILED even though one step passed.

Approach Hints

• Use a hash map/dictionary to group log entries by job name.
• Track max RC and step count per job.
• Apply status logic after processing all entries.
