The Task: Extract and calculate reward points from a single "messy" column (e.g., `'MM:CI:CD'`).

Why you should watch:
โœ… Learn the cleanest way to use STRING_SPLIT.
โœ… Master Conditional Aggregation (no more spaghetti code!).
โœ… Avoid the #1 over-engineering mistake candidates make in FAANG interviews.

Stop struggling with messy dataโ€”master the logic in 5 minutes.

Watch the full solution here:
