Answer:

jspService()

Explanation:

These are the steps in JSP life cycle-

1. We have to convert JSP page to Servlet.

2.Then we compile the JSP page which convert it into test.java

3. In test.java ,we load the classes(test.class) in container.

4. Object(instance) is created in container .

5. Then, we initialize the init() method at the time of servlet generation.  

6. After the initialization,for the requests we use _jspService() method to serve the incoming requests from JSP.

7. When the work of JSP is completed, we remove it from container by the help of jspDestroy() method.

There is no jspService() method in the JSP life cycle.

Andy is trying to put together a holiday gift knapsack (with W=8) for Sarah. He has n items to choose from, each with infinitely
Sever21 [200]

Answer:

See explaination

Explanation:

Given 3 items: {w1 = 1, v1 = 3}, {w2 = 3, v2 = 2}, {w3 = 4, v3 = 3}

Hence OPT(1) = 3, OPT(3) = 2, OPT(4) = 3

Recursive formula for OPT(k) to minimize value is

OPT(k) = INFINITE if k <= 0

= min(3 + OPT(k-1), 2 + OPT(k-3), 3 + OPT(k-4))

Let us calculate OPT(1) to OPT(8)

OPT(1) = 3

OPT(2) = min ( 3 + OPT(1), 2 + OPT(-1), 3 + OPT(-2)) = 6

OPT(3) = 2

OPT(4) = 3

OPT(5) = min ( 3 + OPT(4), 2 + OPT(2), 3 + OPT(1)) = min(6, 8, 6) = 6

OPT(6) = min ( 3 + OPT(5), 2 + OPT(3), 3 + OPT(2)) = min(9, 4, 9) = 4

OPT(7) = min ( 3 + OPT(6), 2 + OPT(4), 3 + OPT(3)) = min(7, 5, 5) = 5

OPT(8) = min ( 3 + OPT(7), 2 + OPT(5), 3 + OPT(4)) = min(8, 8, 6) = 6

Write Python algebraic expressions corresponding to the following statements: (a) The sum of the first five positive integers (b
lbvjy [14]

Answer:

#part a

#sum of first 5 positive number

Sum=5*(5+1)/2

print("sum of first 5 positive integer is: ",Sum)

#part b

# declare age of all

Sara_age=23

Mark_age=19

Fatima_age=31

ave_age=(Sara_age+Mark_age+Fatima_age)/3

print("average age of Sara,mark and Fatima is: ",ave_age)

#part c

#find number of times

no_of_times=int(403/73)

print(" number of times when 73 goes into 403 is: ",no_of_times)

#part d

#find remainder

rem=403%73

print("when 403 is divided by 73 then remainder  is: ",rem)

#part e

#calculate 2 to pawer 10

two_pow=2**10

print("2 to power  10 is: ",two_pow)

#part f

#declare height of both

sara_h=54

mark_h=57

diff_h=abs(sara_h-mark_h)

print("The absolute difference between height of Sara and Mark is: ",diff_h)

#part g

#find the minimum among three

print("lowest price among the three($34.99,$29.95,$31.50) is: $",min(34.99,29.95,31.50))

Explanation:

In part a, sum of first 5 positive number is calculated as 5*(5+1)/2.In part b, add the age of three and divide it  by 3. In part c, use "/" to find number of times 73 goes into 403.In part d, use "%" to find remainder when 403 is divide by 73.In part e, 2 to the 10th power is calculated as 2**10.In part f, use abs() to find the absolute  difference.In part g, min() function is used to find lowest among the 3 prices.

Output:

sum of first 5 positive integer is:  15.0                                                                                  

average age of Sara,mark and Fatima is:  24.333333333333332                                                                

number of times when 73 goes into 403 is:  5                                                                              

when 403 is divided by 73 then remainder  is:  38                                                                          

2 to power  10 is:  1024                                                                                                  

The absolute difference between height of Sara and Mark is:  3                                                            

lowest price among the three($34.99,$29.95,$31.50) is: $ 29.95
