You will create a program that will follow the queuing theory of the Barbershop Problem. You will initially create a flow chart for the assignment to be uploaded to the Queuing Theory Flowchart assignment drop box. In this you will use queues and random number generators to complete this project. You will create three queues
You will create a container for the barbers chairs (list) . The wait times for the barbers will be random. Barber one will be the fastest and barber three will be the slowest. Randomize the wait times accordingly.
The cashier wait times will also vary randomly.

My output should look like this
Enter the size of the list: 8
Enter the contents of the list: 10 1 5 16 61 9 11 1
The list has 8 integers 10 1 5 16 61 9 11 1

Examples:
longestWord(['Python', 'rocks']) returns 5

Using Python provide the implementation of a function called
"isAdjacent" that accepts a string.
The function checks if two adjacent characters in the string are
the same; if they are the same, then return True otherwise return
False. The function should ignore case and check for
non-empty string. If it's an empty string, then return
the message 'Empty string'.
Sample runs:
print( isAdjacent('ApPle')) # True
print( isAdjacent('Python')) # False
print( isAdjacent('')) # Empty string

SOLVE IN C: 6.31 LAB: Print string in reverse
Write a program that takes in a line of text as input, and outputs that line of text in reverse. You may assume that each line of text will not exceed 50 characters.The program repeats, ending when the user enters "Quit", "quit", or "q" for the line of text.
Ex: If the input is:
Hello there Hey quit
then the output is:
ereht olleH yeH
Hint: Use the fgets function to read a string with spaces from the user input. Recall that if a newline character is read from the user input before the specified number of characters are read, the newline character itself is also written into the string.

C++ Assignment.
Design the Weather class that contains the following members:
Data members to store:
- a day (an integer)
- a month (an integer)
- a year (an integer)
- a temperature (a float)
- a static data member that stores the total of all temperatures (a float)
Member functions:
- a constructor function that obtains a day, month, year and temperature from the user. This function should also accumulate/calculate the total of all temperatures (i.e., add the newly entered temperature to the total).
- a static function that computes and displays the day which has the lowest temperature. Note: An array of Weather objects and the size of the array will be passed to this function.
- a static function that computes and displays the average temperature. This function should use a parameter, if necessary.
Design the main( ) function, which instantiates/creates any number of objects of the Weather class as requested by the user (i.e., creates a dynamic array of Weather objects). main( ) should also call appropriate functions to compute and display the day that has the lowest temperature, as well as the average temperature. Your program should include all necessary error checking.
A sample run of this program could be as follows:
How many days => 4
Enter day, month, year, temperature => 29 11 2018 15.6
Enter day, month, year, temperature => 30 11 2018 8.7
Enter day, month, year, temperature => 1 12 2018 3.1
Enter day, month, year, temperature => 2 12 2018 3.5
Lowest temperature = 3.1 C, Day 1/12/2018
Average temperature = 7.7 C
