IPL Match Details
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

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

The first line contains a single integer N, denoting the total no. of matches played. 
Names of teams may contain spaces but will be less than 24 characters
100 >= N >= 0
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

Smallest Missing Number
Given a list of numbers, write a program to print the smallest positive integer missing in the given numbers.
Input

The input will be a single line containing numbers separated by space.
Output

The output should be a single line containing the smallest missing number from given numbers.
Explanation

For example, if the input numbers are 3, 1, 2, 5, 3, 7, 7.
The number 1, 2, 3 are present. But the number 4 is not. So 4 is the smallest positive integers that is missing from the given numbers.
Sample Input 1
3 1 2 5 3 7 7
Sample Output 1
4

Sample Input 2
5 5 2 3 1 8 8 4
Sample Output 2
6

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
So the output should be 
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.
  
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"
Sample Input 
4
0 5
1 0
2 10
3 6
3
0 1
1 2
2 4
Sample Output 
6x^3 + 14x^2 + 2x + 6

Secret Message - 2
Given a string, write a program to print a secret message that replaces characters with numbers 'a' with 1, 'b' with 2, ..., 'z' with 26 where characters are separated by '-'.

Note: You need to replace both uppercase and lowercase
a	b	c	d	e	f	g	h	i	j
1	2	3	4	5	6	7	8	9	10

k	l	m	n	o	p	q	r
11	12	13	14	15	16	17	18

s	t	u	v	w	x	y	z
19	20	21	22	23	24	25	26
Input

The input will be a string in the single line containing spaces and letters (both uppercase and lowercase).
Output

The output should be a single line containing the secret message. All characters in the output should be in lower case.
For example, if the given input is "python", "p" should replaced with "16", similarly"y" with "25","t" with "20","h" with "8","o" with "15","n" with "14". So the output should be "16-25-20-8-15-14".
Sample Input 1
python
Sample Output 1
16-25-20-8-15-14

Sample Input 2
Foundations
Sample Output 2
6-15-21-14-4-1-20-9-15-14-19
