Race conditions are possible in many computer systems. Consider a banking system with two methods: deposit (amount) and withdraw(amount). These two methods are passed the amount that is to be deposited or withdrawn from a bank account. Assume that a husband and wife share a bank account with a balance of $250.00 and that concurrently the husband calls the withdraw () method of $50.00 and the wife calls deposit () of $100.00. Describe how a race condition is possible and can cause an incorrect balance. What might be done to prevent the race condition from occurring?

Topological Sort

Topological sort is a sorting technique that sets up a hierarchy in a process. In this technique, when a directed network has nodes connected by arrows, the root node is placed before the successor node.

Question

Race conditions are possible in many computer systems. Consider a banking system
with two methods: deposit (amount) and withdraw(amount). These two methods are
passed the amount that is to be deposited or withdrawn from a bank account. Assume
that a husband and wife share a bank account with a balance of $250.00 and that
concurrently the husband calls the withdraw () method of $50.00 and the wife calls
deposit () of $100.00.
Describe how a race condition is possible and can cause an incorrect balance. What
might be done to prevent the race condition from occurring?

Conway's Game of Life: This is a zero person game with the following rules: (see Wikipedia for example) Any live cell with fewer than two live neighbours dies, as if by underpopulation. Any live cell with two or three live neighbours lives on to the next generation. Any live cell with more than three live neighbours dies, as if by overpopulation. Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction. Remember the oscillator or blinker of 3 cells.

The fingerprint-based voting application can recognize users based on their fingerprint patterns. Since fingerprint authentication is unique for each person, the system can quickly identify the voters using their fingerprints. Naturally, a voter can vote for a candidate only once. The Admin adds all the names and photos of the candidates nominated for the election. The Admin then authenticates users by verifying their identity proof, and after verification, the voter is registered in the system. Furthermore, the Admin even enters the data when the election will end, after which the system will automatically delete the names and photos of the candidates and voters. The users can log in to the system via the unique user ID and password given by the Admin and then use their fingerprints to vote for their preferred candidate. Once the election is over, and the votes are counted, Both the Admin and users can view the election result using the election ID. In the capacity of a System…
A Python language Programming in Natural Language Many researchers today now use data from Twitter to analyze and predict the future events. Questions such as which place in a country is the happiest one, who will be the next US president and which place has the highest rate of depressed people, sometimes depend on the information extracted from thousands of tweets. In case of predicting the happiest state in the US, NLP experts have a set of words that also contains their rates, respectively. For example, the word “great” may have a rate from a scale of 1 to 10, 10; the word "awesome" may have a rate of 8; the word “sad” may have a rate 1 and so on. By computing the average score of a tweet using this set of words, researchers would now be able to measure and categorize the mood of a tweet depending on a certain threshold. In this problem, you will be an assistant of an NLP expert who will determine the mood of a tweet. The category would be: < 5 is "sad" >= 5 is "happy" Let…
vvvHarry has a big wall clock, that got hit while he was playing. Now, the minute hand doesn't rotate by the angle 2π/3600 each second, but now it moves according to different angle x. You can assume that coordinates of the centre of the clock are (0, 0) and the length of the minute hand is l. One endpoint of the minute hand is always located at the clock centre; the other endpoint is initially located at the point (0, l). One second later, Harry observes that this endpoint is at distance d above the x-axis, i.e., the y-coordinate of this endpoint is equal to d. Harry is curious about where the minute hand will be (specifically, its y-coordinate) after t seconds. Because t can be very large, Harry can't wait for that moment. Please help him to write a python code that prints a single line containing the output.Input: 4 2 2Output4Harry has a big wall clock, that got hit while he was playing. Now, the minute hand doesn't rotate by the angle 2π/3600 each second, but now it moves according…
In programming, we use the mask concept to indicate information that can be shown to the user and information that must be “masked”, that is, hidden. In an implementation of a hangman game, we use a mask to indicate which secret word positions the player has already guessed right (whose the contents must therefore be shown to the player), and which positions must remain hidden. Each time that the player hits a letter of the hidden word, the mask is updated so that it has little dashes in the places of letters that the player has not hit yet and show it, in their proper place, the letters that he already hit it. For example, if the word is "cards", the current mask is: - a - - s and the player guesses the letter "d", the mask should be updated to: - a - ds.Write a function called update_mask that takes as input a string containing the word secret (in the example above, this word would be “cards”), a list whose elements are the characters of the current mask (in the example above…
Suppose a parent is waiting for the termination of its child. How can it get the return status of its child? Consider the last non-zero digit of your arid number. For example, if your arid number is “17-arid-840” then the last non-zero digit is 4. Suppose x represents the value of your last digit. Now write a program that creates as many child processes as the value of x. For each process, you must check whether it is created successfully or not. After creation, each child process will print the message “I am child “count”. (count = 1, 2, 3, … x) and then it will terminate normally using exit(). Count value will be used by each child as exit status value while exiting. After termination of child processes, parent process will check the exit status of each child and will display the status value that was used by the child while exiting. For example, parent can display the following statement for each child: “xxxx: My child has been terminated and its termination code was 3”. In this…
