Time Complexity

In computer science, the computational complexity that is measured in terms of time is referred to as time complexity that defines how long it takes a computer to execute an algorithm. An algorithm's time complexity is measured by the the amount of time required to execute each statement of code in the algorithm. If a statement is set to execute repetitively, the number of times it will be N multiplied by the time it takes to run that function each time is equal .

6. Use a truth table to determine whether the following argument form is valid. Indicate which columns represent the premises and which represent the conclusion, and include a sentence explaining how the truth table supports your answer. Your explanation should show that you understand what is means for a form of argument to be valid or invalid. Argument form: P→ r q→ r ..pvqr
What does a TRC query mean? More precisely, what is the set of answer tuples for a given TRC query? The answer to a TRC query {T| p(T)}, as we noted earlier, is the set of all tuples t for which the formula p(T) evaluates to true with variable T assigned the tuple value t. To complete this definition, we must state which assignments of tuple values to the free variables in a formula make the formula evaluate to true.
