    What type of problem is the change-making problem? - ProProfs

    What type of problem is the change-making problem?

    • Ring puzzle

    • Knapsack

    • Tile puzzle

    • Coin weight

    Correct Answer
    A. Knapsack
    Explanation
    The change-making problem is a type of problem known as the knapsack problem. In this problem, the goal is to determine the minimum number of coins needed to make a certain amount of change. It is similar to the knapsack problem because both involve optimizing the use of limited resources (coins or items) to achieve a specific goal (making change or filling a knapsack). The other options, such as ring puzzle, tile puzzle, and coin weight, are not relevant to the change-making problem.

    What can be used to solve the change-making problem?  - ProProfs

    What can be used to solve the change-making problem? 

    • Skill programming

    • Plotting graphs

    • Dynamic programming

    • Abstract algebra

    Correct Answer
    A. Dynamic programming
    Explanation
    Dynamic programming can be used to solve the change-making problem. This problem involves finding the minimum number of coins needed to make a given amount of change. Dynamic programming is a technique that breaks down a problem into smaller subproblems and solves them in a bottom-up manner, using the solutions of the subproblems to build up the solution to the original problem. In the case of the change-making problem, dynamic programming can be used to calculate the minimum number of coins needed for each possible amount of change, starting from the smallest possible amount and working up to the desired amount.

    Which is a feature of the change-making problem? - ProProfs

    Which is a feature of the change-making problem?

    • Optimal substructure

    • Substructure

    • Time

    • Length

    Correct Answer
    A. Optimal substructure
    Explanation
    The feature of the change-making problem that is being referred to in this question is "Optimal substructure". Optimal substructure means that the optimal solution to a problem can be constructed from optimal solutions to its subproblems. In the context of the change-making problem, this means that the optimal way to make change for a certain amount can be determined by considering the optimal ways to make change for smaller amounts. This property allows for the problem to be solved efficiently using dynamic programming techniques.

    Which is an application of the change-making problem? - ProProfs

    Which is an application of the change-making problem?

    • Nine dart finish

    • Soma cube

    • Colour chart

    • Colour cube

    Correct Answer
    A. Nine dart finish
    Explanation
    The change-making problem refers to finding the minimum number of coins needed to make a given amount of money. The nine dart finish, on the other hand, is a term used in the game of darts to describe a perfect score achieved by hitting the triple 20 segment three times in a row. There is no clear connection between the change-making problem and the nine dart finish, so it is unclear why the nine dart finish is listed as an application of the change-making problem.

    • Length

    • Order

    • Bit

    • Largest integer present

    Correct Answer
    A. Largest integer present
    Explanation
    The numeric value of the input in a numeric algorithm refers to the actual numerical value that is being processed. In this context, "Largest integer present" suggests that the algorithm is specifically looking for the largest integer within the input. This could be important for certain calculations or operations that require identifying the maximum value in a set of numbers.

    A. Length
    Explanation
    The number of bits required to represent the input in a numeric algorithm is called the length.

    Which is the task of deciding whether a given multiset of positive integers can be partitioned into two subsets such that the sum of the numbers in the first subset equals the sum of the numbers in the second subset? - ProProfs

    Which is the task of deciding whether a given multiset of positive integers can be partitioned into two subsets such that the sum of the numbers in the first subset equals the sum of the numbers in the second subset?

    • Set theory

    • Partitioning

    • Segmentation

    • Personalizing

    Correct Answer
    A. Partitioning
    Explanation
    Partitioning is the task of deciding whether a given multiset of positive integers can be divided into two subsets in such a way that the sum of the numbers in one subset equals the sum of the numbers in the other subset. It involves finding a way to split the set into two parts with equal sums. This concept is commonly used in various fields such as computer science, mathematics, and optimization problems.

    Which is a feature of the change-making problem? - ProProfs

    Which is a feature of the change-making problem?

    • Weakly - NP complete

    • Weakly - NP hard

    • Weakly - NP dond

    • NP - complete

    Correct Answer
    A. Weakly - NP hard
    Explanation
    The feature of the change-making problem is that it is weakly NP-hard. This means that while it may not be one of the most difficult problems in the NP-hard category, it still falls within the realm of NP-hard problems. NP-hardness refers to the computational complexity of a problem, indicating that it is at least as hard as the hardest problems in the class NP. Therefore, the change-making problem is not solvable in polynomial time, making it a challenging problem to solve efficiently.

    Which of these is not considered in a change-making problem? - ProProfs

    Which of these is not considered in a change-making problem?

    • Length

    • Bit

    • Order

    • Input

    Correct Answer
    A. Order
    Explanation
    In a change-making problem, the length of the problem, the type of bit used, and the input are all factors that are considered. However, the order is not typically a factor that is considered in this type of problem. The order in which the coins or denominations are used to make change does not affect the solution or the outcome of the problem. Therefore, order is not considered in a change-making problem.
