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.

Tic-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

Anjali Wins

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))

Learning Journal Unit 5

1. Consider the loop from Section 8.3 of your textbook.

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.

Input : the input will be a single line containing a positive integer (N).

Out put : output should be a single line containing years, weeks, days values separated by spaces

N is 1329

Polynomial

Given polynomial, write a program that prints polynomial in Cix^Pi + Ci-1x^Pi-1 + .... + C1x + C0 format.Input

The first line contains a single integer N.

Next N lines contain two integers Pi, Ci separated with space, where Pi denotes power and Ci denotes coefficient of Pi.Output

Print the polynomial in the format Cix^Pi + Ci-1x^Pi-1 + .... + C1x + C0, where Pi's are powers in decreasing order, Ci is coefficient, and C0 is constant. There will be space before and after the plus or minus sign.

If the coefficient is zero, then don't print the term.

If the term with the highest degree is negative, the term should represent -Cix^Pi.

For the term where power is 1, represent it as C1x instead of C1x^1.

If the polynomial degree is zero and the constant term is also zero, then print 0 to represent the polynomial.

For term Cix^Pi, if the coefficient of the term Ci is 1, print x^Pi instead of 1x^Pi.Explanation

If N = 4

For power 0, the coefficient is 5

For power 1, the coefficient is 0

For power 2, the coefficient is 10

For power 3, the coefficient is 6.

Then polynomial represents "6x^3 + 10x^2 + 5"Constraints

N <= 100

0 <= Pi < 1000

-1000 <= Ci <= 1000

Sample Input

Sample Output

6x^3 + 10x^2 + 5
7x^4 + 6x^3 + x^2 + 3x + 2
