Answer:
B.O(2n)
Explanation:
The time complexity of solving towers of hanoi problem recursively is O(2n) because there are two recursion calls in the solution of tower of hanoi.First recursive call to move n-1 disks to from source to helper then the user moves nth disk from source to destination after that recursion moves n-1 disks from helper to destination using source as helper rod.So each recursive call make two more recursive call this makes the time complexity be O(2n).
Answer:
It allows the engine to turn at a lower RPM when the vehicle is traveling at higher speeds. However, when the engine turns more slowly it causes the torque converter to slip, creating heat. ... The solution is to lock the converter. Lock-up eliminates the slippage, which reduces heat and improves fuel economy.

The answer is true. Data redundancies should be avoided,
because redundancy of information or encoded data, may cause inconsistencies
within the database itself and the system and also redundant information can

Answer:
SELECT last_name, job_title, hire_date FROM employee WHERE hire_date>="01-12-2016" AND job_title != "STOCK CLERK" ORDER BY job_title DESC;
Explanation:
The SQL code queries the employee table returning records of the last_name, job_title, and hire_date columns matching the employees hired on or after December 2016 and job titles that are not stock clerks in the employee table.
The WHERE and AND clause is responsible for the condition while the ORDER BY clause returns the query result in the of the job title in descending order.
