Practise making decisions under a time limit
Coding contests give you a reason to apply problem-solving skills within a fixed time, then learn from the approaches you tried.
- Read constraints and prioritise the problems you can solve.
- Choose algorithms with suitable time and space costs.
- Check correctness against edge cases before submitting.
- Review your approach afterwards and revisit problems you could not finish.
