- Create a data type that allows you to insert, remove the maximum, and delete the minimum (all in logarithmic time), as well as locate the maximum and find the minimum (both in constant time). Use two piles as a hint.Q. Write a trigger that checks the length of a contract when a new contract is inserted into longtermcontract table. If this is the first contract between the pharmacy and pharmaceutical company, the length of the contract should not be more than 12 months. If the contract is more than 12 months, the trigger should alter the end date and reduce it to 12 months after the start date. * You have to use BEFORE INSERT ON* THE INSERT STATEMENT IN THE END OF THE GIVEN CODE MUST WORK. GIVEN CODE:-- Do not change the name of the triggerdelimiter //create trigger first_contracts_length_limitation -- do not modify or delete the following lines. Do not write anything after this line.insert into longtermcontract values('parapharmaceutical', '24 South St., Fabreville, QC H7P-E2H', '2020-02-01', '2021-04-01', '***'); SCRIPT:There's a "users" table that has more than 1M rows of "users" information.
