When a website takes in personal information from a user, the owners of the website have no idea what was input, no matter how hard they tried. The information is not stored, and is used by Javascript APIs to locate your address to either ensure that it is valid, or so that you can choose your address.
It's completely safe, and if a website looks really, really sketchy, then just don't give them anything personal.
Another way to identify if a website is safe to give your personal information to is if you see "HTTPS" in the URL at the top of your browser. This means Hyper Text Transfer Protocol Secure, and is the protocol used to transfer information over the internet SECURELY, via encryption that only computers are able to decrypt, and will not show that information to owners of the server/website.
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:
a fix any syntax bugs. I looked it up on the internet so you should be good good luck on your test
