##### Scenario
Pre-employment aptitude screen assessing logical, numerical and verbal reasoning within a strict time limit
##### Question
You have 15 minutes to solve up to 50 items; wrong answers are not penalized. 1. What is the next number in the sequence 3, 6, 12, 24, ___? 2.

Overview: This question evaluates logical, numerical, and verbal reasoning along with rapid pattern recognition and time-limited decision-making relevant to pre-employment aptitude screens for data science roles.
You are taking a timed aptitude test. Wrong answers are not penalized, so you only commit time to questions you are sure you can answer correctly. You are given an array times where times[i] is the minutes needed to answer the i-th sure question, and an integer time_limit (minutes). Find the maximum number of sure questions you can complete without exceeding time_limit. You cannot split a question; you must spend its full time or skip it.
Constraints
- 1 <= len(times) <= 50
- 0 <= times[i] <= 15
- 0 <= time_limit <= 15
- All values are integers (minutes)
Hints
- Sort the times in non-decreasing order.
- Accumulate durations until the next one would exceed time_limit.
- Zero-time questions can always be included.
