Problem

Given a string log_output and an array of strings expected_steps, write a function that returns True if every expected step appears in log_output in the same order, and False otherwise. Each expected step must appear as a substring after the previous matched step, which simulates a simple automated test case verifier.

Examples

Example 1:

Input: log_output = "LOAD OK; INIT OK; RUN OK; COMPLETE OK", expected_steps = ["LOAD OK", "RUN OK", "COMPLETE OK"]
Output: True
Explanation: All expected step results appear in order.

Example 2:

Input: log_output = "LOAD OK; COMPLETE OK; RUN OK", expected_steps = ["LOAD OK", "RUN OK", "COMPLETE OK"]
Output: False
Explanation: The expected steps do not appear in the required order.

Constraints

• 0 <= len(log_output) <= 10^5
• 0 <= len(expected_steps) <= 10^3
• 0 <= len(expected_steps[i]) <= 10^3
• All inputs are strings and matching is case-sensitive
