Construct a DFA with at most 10 states that accepts the set of all strings over the alphabet Σ = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} that are over 9000 (!!!) when interpreted as base 10 integers. Note that the only string starting with 0 that represents a valid integer is 0. Specifically, 0999999999 should not be accepted because it starts with 0. Also, over is strictly larger, so 9000 should be rejected.

Write pseudocode to represent the logic of a program that allows the user to enter a value. the program multiplies the value by 10 and outputs the result.

The computers in the sales department did not have enough data storage capacity to contain all the information the department needed to store, and it was taking a long time for team members to access the data they needed. to fix the problem, the technician installed new, larger hard drives on all the computers.

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system.currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system.currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system.currenttimemillis() just after the end of the algorithm as the elapsed time.
