Answer:

Nonexclusive forwarding

Explanation:

In Nonexclusive forwarding, DNS forwarding is setup so that if the DNS server receiving the forwarded request cannot resolve the name, then the server that originally forwarded the request makes an attempt to resolves it. If that fails, the server sends a request to its designated forwarder.

You are given a list of n positive integers a1, a2, . . . an and a positive integer t. Use dynamic programming to design an algo
Anna11 [10]

Answer:

See explaination for the program code

Explanation:

The code below

Pseudo-code:

//each item ai is used at most once

isSubsetSum(A[],n,t)//takes array of items of size n, and sum t

{

boolean subset[n+1][t+1];//creating a boolean mtraix

for i=1 to n+1

subset[i][1] = true; //initially setting all first column values as true

for i = 2 to t+1

subset[1][i] = false; //initialy setting all first row values as false

for i=2 to n

{

for j=2 to t

{

if(j<A[i-1])

subset[i][j] = subset[i-1][j];

if (j >= A[i-1])

subset[i][j] = subset[i-1][j] ||

subset[i - 1][j-set[i-1]];

}

}

//returns true if there is a subset with given sum t

//other wise returns false

return subset[n][t];

}

Recurrence relation:

T(n) =T(n-1)+ t//here t is runtime of inner loop, and innner loop will run n times

T(1)=1

solving recurrence:

T(n)=T(n-1)+t

T(n)=T(n-2)+t+t

T(n)=T(n-2)+2t

T(n)=T(n-3)+3t

,,

,

T(n)=T(n-n-1)+(n-1)t

T(n)=T(1)+(n-1)t

T(n)=1+(n-1)t = O(nt)

//so complexity is :O(nt)//where n is number of element, t is given sum

Define a function setheight, with int parameters feetval and inchesval, that returns a struct of type heightftin. the function s
ehidna [41]

It is given that the feetVal and inchesVal are parameters of the SetHeight() function. Since the return type of the function is structute, so we need to define a structure.

After that, we need to create a structure variable within the function definition. Now, assign the feet and inches with the feetVal and inchesVal respectively. Finally return the structure variable.

Further explanation:

#include<stdio.h>

//define the structure

typedef struct HeightFtIn_struct {

int feet;

int inches;

} HeightFtIn;

//define the function

HeightFtIn SetHeight(int feetVal, int inchesVal)

{

HeightFtIn Htft; //creating a structure variable of type HeightFtIn

//assign the value of feetVal

Htft.feet = feetVal;  

Htft.inches = inchesVal; //assigning the value of inchesval

//return the structure variable

return Htft;

}

int main(void) {

HeightFtIn studentHeight;

int feet;

 int inches;

printf("Enter the values of feet and the inches: ");

scanf("%d %d", &feet, &inches);

studentHeight = SetHeight(feet, inches);

printf("The student's height is %d feet and %d inches.\n", studentHeight.feet, studentHeight.inches);

return 0;

}

Output:

Enter the values of feet and the inches: 5 9

The student's height is 5 feet and 9 inches.
