In Big-Θ notation, analyze the running time of the following pieces of code/pseudo-code. Describe the running time as a function of the input size (here, n)

int *a = new int [10]; // new is O(1)
int size = 10;
for (int i = 0; i < n; i ++)
{
if (i == size)
{
int newsize = 3*size/2;
int *b = new int [newsize]; // new is O(1)
for (int j = 0; j < size; j ++) b[j] = a[j];
delete [] a; // delete is O(1)
a = b;
size = newsize;
}
a[i] = i*i;
}

You are working as a security analyst in a company xyz that owns the whole subnet range of 23.0.0.0/8 and 192.168.0.0/8. while monitoring the data, you find a high number of outbound connections. you see that ip's owned by xyz (internal) and private ip's are communicating to a single public ip. therefore, the internal ip's are sending data to the public ip. after further analysis, you find out that this public ip is a blacklisted ip, and the internal communicating devices are compromised. what kind of attack does the above scenario depict?

Why would a programmer use the logical operator and in an if statement? a: when an action is to be taken that requires both conditions to be falseb: when an action is to be taken that requires both conditions to be truec: when an action is to be taken that requires the first condition to be falsed: when an action is to be taken that requires the second condition to be truei took the test and the answer is b.

Suppose you have 9 coins and one of them is heavier than others. other 8 coins weight equally. you are also given a balance. develop and algorithm to determine the heavy coin using only two measurements with the of the balance. clearly write your algorithm in the form of a pseudocode using the similar notation that we have used in the class to represent sorting algorithms
