in a divide-and-conquer algorithm, subproblems are chosen primarily to optimize the correctness; runtime often takes care of itself. in dynamic programming, subproblems are usually chosen with runtime in mind, come what may with the correctness. true false
The statement is true. Subproblems in the divide-and-conquer strategy are unrelated to one another. So, it is impossible to take use of overlapping subproblems.
The key concept here is that because our divide and conquer problem has overlapping sub-problems, caching of sub-problem solutions becomes feasible, allowing memoization/tabulation to enter the picture. The CLRS definition of optimal substructure reads: "a problem exhibits optimal substructure if an optimal solution to the problem contains within it optimal solutions to sub-problems." Popular algorithmic paradigm dynamic programming uses a recurring formula to determine the answer. Given that the challenge is divided into smaller sub-problems, it is comparable to the divide and conquer method. Sub-problems are interdependent in dynamic programming, which is the main difference.

a while loop is called a pretest loop because the condition is tested after the loop has had one iteration.
Answer:
False.
Explanation:
A while loop is called a pretest loop because the condition is tested before each iteration of the loop. If the condition is True, the loop will execute, otherwise it will not. This is in contrast to a post-test loop, such as a do-while loop, where the condition is tested after each iteration of the loop.
Given the variables, which boolean condition is true?
int a = 7;
int b = 7;
Answer:
The boolean condition that is true is a == b, which checks if the values of the variables a and b are equal. Since both a and b have been assigned the value of 7, this condition will evaluate to True.

What is the explanation?In this program, the initial value of numA is 4. Then, we start a for loop with count starting at 2, and ending at 4. In each iteration of the loop, numA is incremented by the current value of count. Therefore, the first time through the loop, numA is incremented by 2 to become 6.
The second time through the loop, numA is incremented by 3 to become 9, and the third time through the loop, numA is incremented by 4 to become 13. Finally, numA is printed in each iteration of the loop, so the program will output 9, 11, and 14.
