Weekends

Given two dates D1 and D2, write a program to count the number of Saturdays and Sundays from D1 to D2 (including D1 and D2).

The date in string format is like "8 Feb 2021".Input

The first line of input will contain date D1 in the string format.

The second line of input will contain date D2 in the string format.

Output

The output should be a single line containing two integers separated by space

Explanation

For example, if the given dates are "25 Jan 2021" and "14 Feb 2021", the Saturdays and Sundays dates from "25 Jan 2021" to "14 Feb 2021" are

"30 Jan 2021" is a Saturday

"31 Jan 2021" is a Sunday

"6 Feb 2021" is a Saturday

"7 Feb 2021" is a Sunday

"13 Feb 2021" is a Saturday

"14 Feb 2021" is a Sunday

output

Saturday: 3

Sunday: 3

Sample Input 1

25 Jan 2021

14 Feb 2021

Sample Output 1

Saturday: 3

Sunday: 3

Sample Input 2

25 May 2019

22 Dec 2021

Sample Output 2

Saturday: 135

Sunday: 135

Add two polynomials
Given two polynomials A and B, write a program that adds the given two polynomials A and B.
Input

The first line contains a single integer M. 
Next M lines contain two integers Pi, Ci separated with space, where Pi denotes power and Ci denotes co-efficient of Pi for polynomial A.
After that next line contains a single integer N.
Next N lines contain two integers Pj, Cj separated with space, where Pj denotes power and Cj denotes co-efficient of Pj for polynomial B.
Output

Explanation

If M = 4 and for polynomial A
For power 0, co-efficient is 5
For power 1, co-efficient is 0
For power 2, co-efficient is 10
For power 3, co-efficient is 6.

If N = 3 and for polynomial B
For power 0, co-efficient is 1
For power 1, co-efficient is 2
For power 2, co-efficient is 4.
Then polynomial A represents "6x^3 + 10x^2 + 5", the polynomial B represents "4x^2 + 2x + 1" and the addition of A and B is "6x^3 + 14x^2 + 2x + 6"

Find the perimeter of overlapping rectangles , given the top right and bottom left corners.

While executing the above code, when I am giving the input as ("correct","wrong"). I am getting the output as r. And the expected output is No overlapping.

Please suggest the changes.

Write a GUI to visualize electric field lines of point charges located in a plane.

The functionality the program should provide

• Positive and negative point charges are displayed as blue and red dots, respectively.
• The area of the dot is proportional to the magnitude of the charge.
• 32 field lines emerge from each positive charge
• A left-mouse press and release on a charge deletes the charge
• A left-mouse press not on a charge followed by a mouse motion adds a charge as follows:
•  location of new charge is the mouse-press position.
•  magnitude of the charge is round(dx), where dx is the x-positional difference between location of mouse-release and mouse-press. 
• A left-mouse press on a charge followed by a mouse motion drags the charge resulting in:
• charges being redrawn,
• field lines being recalculated and displayed.
• For better responsiveness, in dragging mode only 8 field lines per charge are used and only the changed elements of the figure are redrawn, not the full figure.

After the Python code below has run, what happens if 'the_file' does not already exist?

try:

   fin = open('the_file', 'r')

except:

  fin = open('the_file', 'w')

fin.close()

Given a M x N matrix, write a program to print the matrix after ordering all the elements of the matrix in increasing order.

Given date-time D, write a program to print the time left for the next New Year.

Write a program that reads all the match outcomes and summarizes the information of all the matches.

Points are given to the teams based on the outcome of the match.

A win earns a team 3 points. A draw earns 1. A loss earns 0.

The following information is expected:

MP: Matches Played

W: Matches Won

D: Matches Drawn (Tied)

L: Matches Lost

P: Points

see sample output for better understanding.

The team information should be displayed in descending order of points.Input.

100 >= N >= 0 HINT:you can maintain all match outcomes in dictionaries.

Sample Input

6

CSK;RR;loss

RR;DD;draw

MI;KKR;win

KKR;RR;loss

CSK;DD;draw

MI;DD;draw

Sample Output

Team: RR, Matches Played: 3, Won: 2, Lost: 0, Draw: 1, Points: 7

Team: MI, Matches Played: 2, Won: 1, Lost: 0, Draw: 1, Points: 4

Team: DD, Matches Played: 3, Won: 0, Lost: 0, Draw: 3, Points: 3

Team: CSK, Matches Played: 2, Won: 0, Lost: 1, Draw: 1, Points: 1

Team: KKR, Matches Played: 2, Won: 0, Lost: 2, Draw: 0, Points: 0
