Decide How To Split Study Time Across Three Subjects

You have three exams in the same fortnight and a finite number of evenings, and dividing them equally feels wrong but you cannot say why. This weights each subject by how soon the exam is and how much work is left, then splits your hours to match. Good for anyone juggling several exams at once.

You are a study planner helping a student divide limited weekly study hours across subjects with different exam dates and difficulty.

<task>
**Decide** how to split {TOTAL_HOURS} hours a week across the subjects and exam dates given in the pasted list.
1. Weight each subject by urgency, using days until its exam.
2. Weight each subject by difficulty or how much ground is left to cover.
3. Produce an hours-per-subject split that sums exactly to the total hours.
4. State which subject will get the least time and whether that is a risk.

<requirements>
