Draw flow charts to find whether the sum of two numbers is greater than 50
Days Conversion
Given a number of days (N) as input, write a program to convert N to years (Y), weeks (W), and days (D).
Input
The input will be a single line containing a positive integer (N).
Output
The output should be a single line containing years, weeks, days values separated by spaces.
Explanation
For example, if the given number of days (N) is 1329.
1329 = 365*3 + 33*7 + 3
So the output is 3 years 33 weeks 3 days
Sample Input 1
1329
Sample Output 1
3 years 33 weeks 3 days
Sample Input 2
960
Sample Output 2
2 years 32 weeks 6 days
Modify class for Client that it only shows "Client creating" on screen for the object initialization only.
Create a static integer field that keeps a count across all instances(objects) of a class. Create 3 or 4 object in derived class and then check total instances.

there is some error in the testcases, help me for getting this out.
Matrix Rotations
You are given a square matrix A of dimensions NxN. You need to apply the below given 3 operations on the matrix A.
Rotation: It is represented as R S where S is an integer in {90, 180, 270, 360, 450, ...} which denotes the number of degrees to rotate. You need to rotate the matrix A by angle S in the clockwise direction. The angle of rotation(S) will always be in multiples of 90 degrees.
Update: It is represented as U X Y Z. In initial matrix A (as given in input), you need to update the element at row index X and column index Y with value Z.
After the update, all the previous rotation operations have to be applied to the updated initial matrix.
Querying: It is represented as Q K L. You need to print the value at row index K and column index L of the matrix A. Input
The first line contains a single integer N.
Next N lines contain N space-separated integers Aij (i - index of the row, j - index of the column).
Next lines contain various operations on the array. Each operation on each line (Beginning either with R, U or Q).
-1 will represent the end of input.Output
For each Query operation print the element present at row index K and colum index L of the matrix in its current state.Explanation

Initial Matrix
1 2
3 4
For R 90, clockwise rotation by 90 degrees, the matrix will become
3 1
4 2
For Q 0 0, print the element at row index 0 and column index 0 of A, which is 3.
For Q 0 1, print the element at row index 0 and column index 1 of A, which is 1.
Again for R 90, clockwise rotation by 90 degrees, the matrix will become
4 3
2 1
For Q 0 0, print the element at row index 0 and column index 0 of A, which is 4.
For U 0 0 6, update the value at row index 0 and column index 1 in the initial matrix to 6. So the updated matrix will be,
6 2
3 4
After updating, we need to rotate the matrix by sum of all rotation angles applied till now(i.e. R 90 and R 90 => 90 + 90 => 180 degrees in clockwise direction).
After rotation the matrix will now become
4 3
2 6
Next for Q 1 1, print the element at row index 1 and column index 1 of A, which is 6.

a plaintext ‘university’
Explain and Use Vigenere cipher to encrypt the message
“homework” using keyword “student”.

is 4
8. Explain and Use Keyed columnar transposition cipher to encrypt

– If a programmer chooses java, a special approach is used. Identify one feature of this special approach.
Why Is Method main Declared static?
prefixes = 'JKLMNOPQ'
suffix = 'ack'
for letter in prefixes:
print(letter + suffix)
Put this code into a Python script and run it. Notice that it prints the names "Oack" and "Qack".
Modify the program so that it prints "Ouack" and "Quack" but leaves the other names the same.
Include the modified Python code and the output in your submission.
2. Give at least three examples that show different features of string slices. Describe the feature illustrated by each example. Invent your own examples. Do not copy them for the textbook or any other source.
