Database: tracking_software_problems
Question: Which problems were reported before the minimum date of problem reported by the staff Lysanne Turcotte? Give me the ids of the problems.
SQL: select t1.problem_id from problems as t1 join staff as t2 on t1.reported_by_staff_id = t2.staff_id where date_problem_reported  <  ( select min(date_problem_reported) from problems as t3 join staff as t4 on t3.reported_by_staff_id = t4.staff_id where t4.staff_first_name = "lysanne" and t4.staff_last_name = "turcotte" )
