Let's consider a long, quiet country road with houses scattered very sparsely along it. (We can picture the road as a long line

segment, with an eastern endpoint and a western endpoint.) Further, let's suppose that despite the bucolic setting, the residents of all these houses are avid cell phone users. You want to place cell phone base stations at certain points along the road, so that every house is within four miles of one of the base stations. Give an efficient algorithm that achieves this goal, using as few base stations as possible.

Answer:

Follows are the solution to these question:

Explanation:

A simple gullible algorithm is present. Let h mark the house to the left. Then we put a base station about 4 kilometers to the right. Now delete and repeat all the houses protected by this base station. In this algorithm, they can simply be seen to position baselines at b1, . . , bk as well as other algorithms (which may be an optimum algorithm) at b'_{1}, \ . . . . . . ,b'_{k'}  and so on. (from left to right)   b_1 \geq b'_{1},\ \  b_2 \geq b'_{2} That's why k \leq k'.

Assume that ip has been declared to be a pointer to int and that result has been declared to be an array of 100 elements . Assum
Bogdan [553]

Answer:

The expression of this question can be given as:

Expression:

*ip + 1

Explanation:

In this question, it is given that ip variable has been declared and initialized and the ip variable is in the first half of the array. It finds the expression whose value is after the element of the array that ip points. So the expression to this question is *ip + 1. Where * is used to define ip variable as a pointer and its value is increased by 1 that is given in the question.

In python:
Misha Larkins [42]

Answer:

Following are the code to this question:

list_val = input()#defining a integer variable for input value

test_grades = list(map(int, list_val.split()))#defining test_grades as a list

sum_extra = -999 #defining sum_extra that holds negative integer value

sum_extra = 0#defining sum_extra that holds value

for y in range(len(test_grades)):#defining a for loop to check range of list  

   if(test_grades[y] > 100):# defining if block that check list value is greater then 100

       sum_extra = sum_extra + (test_grades[y] - 100)#use sum_extra variable to hold extra value and add this value

print('Sum extra:', sum_extra)#print value

Output:

101 83 107 90

Sum extra: 8

Explanation:

In the above code a, "list_val" variable is declared, that uses an input method to input the values and declared a "test_grades" variable that uses a list method to add all values in the list.

In the next step, the "sum_extra" variable is declared, which holds some values and defines a for loop to check the range of the "test_grades", and define a if block, that checks list value is greater than 100. If the condition is true, it will remove the extra value, and add it into the sum_extera variable and add its value, and at the last use, print variable to print its value.

Write java code to create a new class called "student". an object of the student class has attributes like student id, name and
Fiesta28 [93]
Here you go. I added a constructor and a toString overload to make the object creation and printing as easy as possible.

public class student {
    private String _id;
    private String _name;
    private String _address;

    public student(String id, String name, String address) {
        _id = id;
        _name = name;
        _address = address;
    }

    public String toString() {
        return "Id: " + _id + "\nName: " + _name + "\nAddress: "+ _address;
    }

    public static void main(String[] args) {
        student s1 = new student("S12345", "John Doe", "Some street");
        System.out.println(s1);
    }
}

You work for a retail clothing chain whose primary outlets are in shopping malls and are conducting an analysis of your customer
Alla [95]

Answer: Identifying sequences

Explanation:

Since the user wants to know if there are any particular activities that the customers engage in, or the types of purchases made in the month before or after purchasing select items from your store, therefore, the data mining software can be used in identifying sequences.

In this case, the data mining software can't be used in classifying data whether into structured or unstructured data. Furthermore, the identification of clusters and associations aren't the correct answers.

Therefore, the best option is B.
