How to use python to check if a string is anagram?

Anagram is a word or phrase can be formed by rearranging the letters of another word or phrase. For example, carthorse is anagram of horsecars. Blanks within a phrase will be ignored. orchestra and horse cart are also anagrams.

Write a program that reads a list of phrases and print all pairs of anagram is demonstrated as follow (it will not work for upper case and lower case checking , "A" is different from "a" in the current program):

Sample input: 
carthorse
horse
horse cart
I do not know u
ok i now donut
orchestra
Sample output:
carthorse = horse cart
carthorse = orchestra
horse cart = orchestra
i do not know u = ok i now donut

Please get the code and sample input file as below (there are both python and c++ version):

AIO Sample question with answer 2: Sitting or Standing?

Input File: sitin.txt

Output File: sitout.txtTime Limit: 1 second
Input
Output

A local musician is putting on a concert to raise money for charity. The concert will be held in the town hall, a spacious venue perfectly suited for such an event. There are r rows of seats, each containing exactly s seats. At most one person can sit on a single seat (that is, two people cannot share a seat).

There is a problem - the concert may have been overbooked! This means that if everybody who bought tickets comes to the concert, some of them might have to stand. Now the musician has aproached you, not for advice, but for the answer to the following question: if everybody who bought tickets arrives and tries to find a seat, how many people will end up sitting, and how many people will be standing?

The first line of the input file will consist of the two integers r and s: the number of rows and the number of seats per row in that order. It is guaranteed that 0 <= r, s <= 10,000. The second line will contain a single integer between 0 and 1,000,000,000: the number of tickets that have been bought.

Your output file should consist of two integers separated by a space: the number of people sitting and standing respectively.

Remember, everybody tries to sit if they can. If the concert has been overbooked, you will not be able to seat them all.

I had try the question using Python. 

The logic of program should be as below:

• get input data (number of seats per rows, number of rows and number of tickets sold)
• calculate the number of seats in total provided, number of tickets sold, get the number of standing people, number of sitting people
• output the result to file

You may get the code from here python code

or

viewing the python code as follows:

#################################################################################

# open the input file to obtain the number of rows and seats

with open('sitin.txt', 'r') as inputFile1: 

    mylist = list(inputFile1) # assign the row to list

    

inputFile1.close() # remember that always close the file

# the input data is optained row by row and is assigned to list

# first list is first line of input file (no.of.rows and seats)

# second list is second line of input file (no.of.tickets sold)

row, seats = mylist[0].split(' ', 1)  # split the first element of list to get row and seats per row

tickets = mylist[1] # second row is only have the no.of.tickets sold

# calculate the total number of seats provided

# need to type casting the row and seats to integer datatype

# if number of seats is smaller or equal to number of tickets sold, number of people sitting = number of sets, the rest will be standing

# if number of seats is larger than the tickets solds, number of people sitting equal to number of tickets sold , and no people is standing

noOfSeats = int(row) * int(seats)

noOfTickets = int(tickets)

if noOfSeats <= noOfTickets:

    standing = noOfTickets - noOfSeats

    seatNo = noOfSeats

else:

    seatNo = noOfTickets

    standing = 0

# open output file, and write the result into it

# must close the file

outputFile = open('sitout.txt','w') 

outputFile.write(str(seatNo) + ' ' + str(standing)); 

outputFile.close()

How I check my answer ?

Well.
That is quite challenging to do mathematics questions.
There  might be many solutions for one one mathematic question.
Sometimes, you may need more time to study the question to get optimal solutions.
However it might quite frustating if you do not know whether that is correct answer or solutions after you trying the questions for more than half an hour.

To ensure the "accuracy", I will normally checking my answer using computer.
It is not encouraging to do exhaustive method to do checking on hand, but we might use it by the help of computer.

Recently, I find out it is quite challenging to solve question regarding of disibility question.
You may check on the question in my other posts.

Answer for revision book 5

I would like to introduce another method if you wish to check how accurate is your answer.
I will do some coding, in language C++ for this question.
I know you may ask what is C++ ? It is a programming language you may use to do a program.
Simply you may find some C++ online compiler and paste the code and run it.

Steps:
1. Please download the code file. If you cant view the file, you may right click the file, and click on open with then choose notepad to open the code
    Divisible question code
2. Please click on this link to open the online compiler
    C++ online compiler i am using
3. Copy and paste the code in C++ online compiler. Then click run.

You may get your answer.

You may modify the code when you have to check your answer for similar question but different value.

Have fun!
