Abhinav and Anjali are playing Rock-Paper-Scissors game. Rock-Paper-Scissors is a hand game usually played between two people, in which each player simultaneously forms one of three shapes with an outstretched hand. These shapes are "rock", "paper" and "scissors". Based on the shapes the player chooses the outcome of the game is determined. A rock beats scissors, scissors beat paper by cutting it, and paper beats rock by covering it. If the same shape is chosen by both of the players, then it is a tie. Write a program to decide the winner of each round of the game based on the shapes the players chose.

Given Inputs:

1. Rock, Paper output is "Anjali wins"
2. rock, scissors output is "Anjali wins"

Add two polynomials

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

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

Print the addition of polynomials A and B.

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

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

Mean, Median and Mode

Given a list of integers, write a program to print the mean, median and mode.

Mean - The average value of all the numbers.

Median - The mid point value in the sorted list.

Mode - The most common value in the list. If multiple elements with same frequency are present, print all the values with same frequency in increasing order.

See Sample Input/Output for the output format.

Sample Input 1

2 4 5 6 7 8 2 4 5 2 3 8

Sample Output 1

Mean: 4.67

Median: 4.5

Mode: 2

Sample Input 2

2 6 3 1 8 12 2 9 10 3 4

Sample Output 2

Mean: 5.45

Median: 4

Mode: 2 3

The output should be in this function format given below :

def find_mean(num_list):

  # Complete this function

def find_median(num_list):

  # Complete this function

def find_mode(num_list):

  # Complete this function

num_list = list(map(int, input().split()))

# Call the appropriate functions and print the results

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 '-'.

a b c d e f g h i j k l m n o p q r s t u v w x y z

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

Input

Input will be a string in single line containing spaces and letters both uppercase and lowercase.

Output

Output should be a single line containing secret message. All characters in output should be in lower case.

Explanation

For example, if 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 output should be "16-25-20-8-15-14".

Along with the encrypted copy, some mysterious person has also given you the following documents:

helloworld.txt -- Maybe this file decrypts to say "Hello world!". Hmmm.

Given a sentence as input, print all the unique combinations of the words of the sentence, considering different possible number of words each time (from one word to N unique words in lexicographical order).Input

The input will be a single line containing a sentence.Output

The output should be multiple lines, each line containing the unique combination from one word to N words in lexicographical order.Explanation

For example, if the given sentence is "apple is a fruit".

All possible one-word unique combinations are

a
apple
fruit
is

All possible two words unique combinations are

a apple
a fruit
a is
apple fruit
apple is
fruit is

All possible three words unique combinations are

a apple fruit
a apple is
a fruit is
apple fruit is

All possible four words unique combinations are

a apple fruit is

Sample Input 1

apple is a fruit

Sample Output 1

a

apple

fruit

is

a apple

a fruit

Given a sentence as input, print all the unique combinations of N words in lexicographical order.Input

The first line of input will be containing a sentence.

The second line of input will contain a positive integer.Output

The output should be multiple lines, each line containing the unique combination of N words in lexicographical order.Explanation

For example, if the given sentence is "apple is a fruit", and N is 3, the possible unique combination of three words are (a, apple, fruit), (a, apple, is), (a, fruit, is), (apple, fruit, is). So the output should be

a apple fruit
a apple is
a fruit is
apple fruit is
