Which statement outputs a double value in a field of nine characters with three digits after the decimal point?
zimovet [89]

Answer:

Console.WriteLine("Format Double: {0:n3}", num); //formatting output with 3 digit decimal point

Explanation:

Following are the program in c#

using System; // namespace  

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace Tasks

{

   class Program 2 // program2

   {        

                 

       static void Main(string[] args) // Main function

       {

 

           double num = 958254.73789621;   // variables          

           Console.WriteLine("Format Double: {0:n3}", num); //formatting output with 3 digit decimal point

           Console.Read();

       }

   }

}

Output:

Format Double : 958254.737

Here we have declared  a variable num of type double which store the value num=958254.73789621. To do format with the double number i used a syntax {0:n3}. This syntax {0:n3}is separated with :(colon) here 0 represent the value before the decimal point that is 958254 and n3 represent the value upto 3 decimal points. Hence this statement give the output with three digit after the decimal point .

The Subset Sum problem is a generalization of the Knapsack problem. Group of answer choices True False g
Katarina [22]

Answer: True

Explanation:

Subset sum problem and Knapsack problem can be solved using dynamic programming.

In case of Knapsack problem there is a set of weights associative with objects and a set of profits associated with each object and a total capacity of knapsack let say C. With the help of dynamic programming we try to include object's weight such that total profit is maximized without fragmenting any weight of objects and without exceeding the capacity of knapsack, it is also called as 0/1 knapsack problem.

Similar to knapsack problem, in subset sum problem there is set of items and a set of weights associated with the items and a capacity let say C, task is to choose the subset of items such that total sum of weights associated with items of subset is maximized without exceeding the total capacity.

On the basis of above statements we can say that subset sum problem is generalization of knapsack problem.
