Answer: web server
Explanation:
When you go to a website, your web browser requests a web page from the web server. For this to happen, the IP address for the webpage has to be identified first, tmaftee which the browser will request appropriate data from the web server.
Such request comes in form of data packet and takes place through HTTP and.utnhas all the necessary information that is needed by the web server for the delivery of the webpage data.
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
Answer:
Both codes are correct.The value of even is true when the number is even.
Explanation:
Code 1:
number %2 ==0 means that when dividing number by 2 is the remainder coming out is zero.If it is true then even becomes is true if it is false then else statement is executes in which even becomes false.Means the number is odd.This code is simple and easy to understand.
Code 2:-
This code is a bit tricky and takes time to understand.even becomes true
when the number is divisible by 0 and false when it is not.
Answer:
Option: Making a choice
Explanation:
In a problem solving process, it starts with defining a problem which is the first step that we need to identify the issue.
After that, we should gather the information on the issue that we identify. For example, we are root cause of the problem, what are the possible solutions etc.
Next, we evaluate the information that we collect (e.g. pro and cons of a particular solution).
Next, we make a choice on the solution that we are going to take after further evaluation on all the options we have.
Only after we make a choice, then we can take action based on our chosen solution to solve the problem.
