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.

Input

The input will be a single line containing space-separated integers.Output

The first line of output should contain the mean, round off the value to 2 decimal places.

The second line of output should contain the median, round off the value to 2 decimal places.

The third line of output should contain the mode.

Mean should always be a float value.

Median should be a float value when there are even number of elements, otherwise should be an integer value.

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

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

Describe the difference between a chained conditional and a nested conditional. Give your own example of each. 

Deeply nested conditionals can become difficult to read. Describe a strategy for avoiding nested conditionals. Give your own example of a nested conditional that can be modified to become a single conditional, and show the equivalent single conditional. 

Anti-Diagonals

Given a MxN matrix,write a program to print all Anti-Diagonals elements of matrix

Input

The first line of input will contain a M, N values separated by space.

The second line will contain matrix A of dimensions MxN.

Output

The output should contain anti-diagonal elements separated by a line.

Explanation

For example, if M = 4, N = 4

Matrix A:

4 4

1 2 3 4

5 6 7 8

9 10 11 12

13 14 15 16

So the output should be

a.      Output "GREATER" if a given integer <num> is greater than 90.

Write a functionthat takes unsorted list as a parameter and return a sorted listin decending order(Do notuse any built-in function)

Create a list which contains the first three odd positive integers and a listbwhich contains the first three even positive integers.a= [1, 3, 5]b= [2, 4, 6]Create a new listcwhich combines the numbers from both lists (orderis unimportant).Find the Maximumvalue in list c (Donot use built-in function)Insert fourth element in listc42Append7,8and9to the end ofc.Print the first twoelements ofc.Print the last element ofbwithout using its length.Print the lengthofa

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.Input

The input will be a single line containing space-separated integers.Output

The first line of output should contain the mean, round off the value to 2 decimal places.

The second line of output should contain the median, round off the value to 2 decimal places.

The third line of output should contain the mode.

Mean should always be a float value.

Median should be a float value when there are even number of elements, otherwise should be an integer value.

See Sample Input/Output for the output format.Explanation

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

The average of all the numbers is 4.67.

After sorting the array,

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

Replace Elements with Zeros
Given a MxN matrix, write a program to replace all elements that do not belong to principal-diagonal & anti-diagonal with Zeros.
Principal-diagonal elements are the set of elements of a matrix that lie on the line joining the top left corner to the bottom right corner.
Input

The first line of input will contain two space-separated integers, denoting MxN matrix.
The next M lines will contain N space-separated integers.
