What are the time complexities of these methods?
Briefly explain how you counted, for the case below.
Be careful about power function. You may want to start with a few examples (k=1, k=2, k=3, and figure out the pattern). Explain your answer.
void magic(int n, int k)
{
for (int i=1; i<=n; i++)
{
int p = pow(i, k);
for (int j=1; j<=p; j++)
{
// printing stuff
}
}
}

Analyze the following code and provide a "Big-O" estimate of its running time in terms of n. Explain your analysis. Assume k is a constant given by the problem. for (i=1; i<=n; i++) p = pow(i,k); // p = i to the power of k for (j=1; j<=p; j++) Some O(1) work end for end for
this can be done in one class or two separate classes,in java
thanks!
You will implement and test several short recursive methods below. With the proper use of recursion, none of these methods should require more than a dozen lines of code. Test all these in the same class. Keep adding methods and testing until all are working 5. A Fractal Pattern Examine this pattern of stars and blanks, and write a recursive method that can generate patterns such as...
Questions What is the command to compile the files with extra symbols that are useful for GDB? What's the address of stuff? What's the address of stuff[0]? Do we expect these to be the same? Why? Explain what the [ ] operator does in C. In Blowfish_Init( ), what is the value of key? What command(s) did you type in order to learn this? In Blowfish_Init( ), what are the values of i and j after the nested for loops...
4. Big-Oh and Rune time Analysis: describe the worst case running time of the following pseudocode functions in Big-Oh notation in terms of the variable n. howing your work is not required (although showing work may allow some partial t in the case your answer is wrong-don't spend a lot of time showing your work.). You MUST choose your answer from the following (not given in any particular order), each of which could be re-used (could be the answer for...
For the following program fragment give a Big-O analysis of the running time. Briefly explain your answer: int t = 0; for(int i=1; i <= n; i++) for(int j=1; j <= i*i; j++) if(j % i == 0) t++; What I have so far, O(1) + O(n) + O(n2) + O(1) + O(1) Drop Low order terms: O(n) + O(n2) And I believe the final answer to be O(n3), but not sure if just drop the O(n) or...
Help pls! and kindly explain how you do this as well. Thaank you Write a program to test whether a square is a 3x3 magic square. A magic square is a grid with 3 rows and 3 columns, like the figure below. A magic square has the following properties: the grid contains only the numbers 1 through 9 the sum of each row, each column, and each diagonal all add up to the same number Notes: I have provided the...
You will invent two sequences of increments for program them into the code shell provided in the attachment. For examples, suppose Shell increments had not been invented, then you could invent them, and your sequence would be for a given sequence length, N,N/2, N/4, N/8 .... 1 You will program these into the functions provided and execute the code and it will produce BIg O graphs. You can use excel or DSWB to view these graphs and determine the Big...
C Programming - RSA encryption Hi there, I'm struggling with writing a C program to encrypt and decrypt a string using the RSA algorithm (C90 language only). It can contain ONLY the following libraries: stdio, stdlib, math and string. I want to use the following function prototypes to try and implement things: /*Check whether a given number is prime or not*/ int checkPrime(int n) /*to find gcd*/ int gcd(int a, int h) void Encrypt(); void Decrypt(); int getPublicKeys(); int getPrivateKeys();...
you will analyse two algorithms for finding the median of an array of integers. You will compare both algorithms in terms of timing, and hopefully design a hybrid algorithm that uses both, depending on input size. You will write a report describing your experiments and results. the following Java program implements two algorithms for finding the median of an array of integers. The first uses merge sort, and the other implements the recursive linear time selection algorithm, the task is...
