Numbers in String - 1

Given a string, write a program to return the sum and average of the digits of all numbers that appear in the string, ignoring all other characters.

Input

The input will be a single line containing a string.

Output

The output should contain the sum and average of the digits of all numbers that appear in the string.

Note: Round the average value to two decimal places.

Explanation

For example, if the given string is "I am 25 years and 10 months old", the digits of all numbers that appear in the string are 2, 5, 1, 0. Your code should print the sum of all digits(8) and the average of all digits(2.0) in the new line.

Sample Input 1

Ordered Matrix

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

Input

The first line of input will contain two space-separated integers, denoting the M and N.

The next M following lines will contain N space-separated integers, denoting the elements of each list.

Output

The output should be M lines containing the ordered matrix.

Note: There is a space at the end of each line.

Explanation

For example, if the given M is 3 and N is 3, read the inputs in the next three lines if the numbers given in the next three lines are the following.

1 20 3
30 10 2
5 11 15

By ordering all the elements of the matrix in increasing order, the ordered matrix should be

1 2 3
5 10 11
15 20 30

Sample Input 1

3 3

1 20 3

30 10 2

5 11 15

Sample Output 1

1 2 3

5 10 11

15 20 30

Sample Input 2

88 17 38 72 -10

Sample Output 2

-50 -20 -10 3 17

IPL Match Details

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

Points are given to teams based on outcome of 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

team information should be displayed in descending order of points.

If there are no teams to print in summary, print "No Output".

Constraints

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

Weekends

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

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

Input

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

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

Output

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

Explanation

For example, if 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 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

Secret Message - 1

Given a string, write a program to mirror the characters of the string in alphabetical order to create a secret message.

Note: Mirroring the characters in alphabetical order replacing the letters 'a' with 'z', 'b' with 'y', ... , 'z' with 'a'. You need to mirror both uppercase and lowercase characters. You can ignore mirroring for all characters that are not letters.

abcdefghijklm

zyxwvutsrqpon 

nopqrstuvwxyz

mlkjihgfedcba

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.

A lady behaves like a teacher in a classroom, mother or daughter in a home and 

customer in a market. Here, a single person is behaving differently according to the 

situations. Consider a above real-life example and which concept you will use in cpp. 

Elaborate the concept.

Write a C++ program that will take in two strings str1[20] and str2[20] from user and do the following:

(a)  Copy str1 to str2

(b) Compare str1 and str2, display 1 if str2 is greater and display 2 if str1 is greater.   

Write a C++ program that will accept three integers and return the average value of these integers. Make use of array num[ ] in your program.

Write a Program that implements Base class calculator and a Derived class scientific calculator, The Derived class should take the basic operations i.e. add, divide, subtract from calculator. However it should have its own methods such as square, cube, and average and display method to display all these calculation for integer numbers. A main class with main method and create an object of base class and call the display method.
