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.

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.

Temperature Conversion
You are given the temperature T of an object in one of Celsius, Fahrenheit, and Kelvin scales.
Write a program to print T in all scales viz Celsius, Fahrenheit, and Kelvin.
Formula to convert from Fahrenheit F to Celsius C is C = (F - 32) * 5 / 9.
Formula to convert from Kelvin K to Celsius C is C = K - 273.
Here "C", "F", "K" represent that the temperature scale is in Celsius, Fahrenheit and Kelvin scales respectively.
The input contains the temperature (a number) and the unit of the temperature scale (C, F, K) without any space.
The output contains temperature in Celsius, Fahrenheit and Kelvin scales in each line in the format similar to input and the value of the temperature is rounded to 2 decimal places.Input
The first line of the input contain a temperature Value in one of Celsius, Fahrenheit, and Kelvin scales.Output
The first line of output should contain the Celsius value and the unit of the Celsius without any space.
The second line of output should contain the Fahrenheit value and the unit of the Fahrenheit without any space.
The third line of output should contain the Kelvin value and the unit of the Kelvin without any space.Explanation
For example, if the given temperature Value is 25C then Celsius value is 25.0C, Fahrenheit value is 77.0F, and Kelvin value is 298.0K.

276.06KTic-Tac-Toe game
Abhinav and Anjali are playing the Tic-Tac-Toe game. Tic-Tac-Toe is a game played on a grid that's three squares by three squares. Abhinav is O, and Anjali is X. Players take turns putting their marks in empty squares. The first player to get 3 of her marks in a diagonal or horizontal, or vertical row is the winner. When all nine squares are complete, the game is over. If no player has three marks in a row, the game ends in a tie. Write a program to decide the winner in the Tic-Tac-Toe game.
Input
The input will be three lines contain O's and X's separated by space.
Output
The output should be a single line containing either "Abhinav Wins" or "Anjali Wins" or "Tie".
Explanation
For example, if the input is
O X O
O X X
O O X
as three of O's are in vertical row print "Abhinav Wins".
Sample Input 1
O X O
O X X
O O X
Sample Output 1
Abhinav Wins
Sample Input 2
O O X
X X O
X O O
Sample Output 2

Coding
The minimal requirements of your program are:
• Present the user with a menu, wherein s/he may decide:
◦ Which dishes to make (with up to four dishes, this means up to 4 threads)
◦ The number of each dish to prepare (ideally a separate number for each dish)
◦ How often should progress be reported? (Explained further below)
• Start a thread for each dish
◦ Each type should be implemented into its own thread, since it has its own lock requirements
◦ Each dish tries to report upon completing one (subject to above/below)
◦ Each dish type always reports when completed its iterations
▪ Obviously there's no reporting if none are being made at all
• The program then reports on the total number of dishes produced
• If this isn't obvious, increasing the tally and output are also a 'resource'
Additional notes:
Write your threads immensely clearly, and comment it.
• Comment usefully. Don't add nonsense like identifying that a loop “loops”, or that .lock() “locks”
• Also, proper indentation, please?
Obviously, you'll have several .java files for this (if using Java).
Pseudo Code:
import threading
todo=2000000
confirmed=0
lock=threading.Semaphore() #We had some interesting options here
def worker(id):
global todo, confirmed
print("\t"+str(id)+" thinking...")
while True:
#We could do extra work here
lock.acquire() #Either acquire
the lock, or block until it's ready
if todo==0:
break
todo-=1
confirmed+=1
lock.release()
#We could also do work here
print("\t"+str(id)+" completed!")
t1=threading.Thread(target=worker, args=(1,))
t2=threading.Thread(target=worker, args=(2,))
t1.start()
t2.start()
t1.join()
t2.join()
print("Done!\n"+str(confirmed))

Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, I-405 services I-5, and I-290 services I-90.
Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west.
Ex: If the input is:
90the output is:
I-90 is primary, going east/west.Ex: If the input is:
290the output is:
I-290 is auxiliary, serving I-90, going east/west.Ex: If the input is:
0the output is:
0 is not a valid interstate highway number.Write a program that finds the area of circle, triangle, rectangle and square using a function named area. In this program, use a single class named shape which contains various implementations of ‘area’. Your program should dynamically decide which shapes area has to be found depending on the type of input. The radius is float value, base and height of triangle are double values, sides of rectangle and square are integer values.
