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:
Option (c) Remote code exploits aim to escalate attackers’ privileges, while XSS attacks aim to gain access only
Explanation:
- XSS stands for Cross-site Scripting. In this types of attacks, a malicious code is injected in the trusted web sites and it sends the malicious code into the users. The users think that the genuine code was sent but not.
- This involves sending server side scripts which are executed by the user and these may even change the html pages too.
- Remote code exploitation means the user can inject the code and try to gain access. Usually, all the programming languages have evaluation functions if used the user can try to gain the access with this evaluation functions.
- This can lead to the compromise of the whole web server too.So, it is not a good practice to use the evaluation functions by the developers.
- In this type of attack, the attacker tries to inject the code remotely.
- Option (c) is correct and options (a),(b) and (d) are wrong options.
