- 1. Front-Running Detector Front-running is defined as trading a stock or another financial asset by a broker who has inside knowledge of a future transaction that is about to affect its price substantially. It is illegal and unethical. Here's an example of front-running: Say a trader gets an order from a broker to buy 50,000 shares of Tesla. Such a huge purchase is bound to drive up the price of the stock immediately, at least in the short term. The trader sets aside the broker request for a minute and first buys some Tesla stock for their own portfolio. Then the broker's order is executed. The trader could then immediately sell the Tesla shares and collect a profit. The trader has made a profit based on information that was not public knowledge. Your task is to create a Front-Running Detector that will process option trade data from different exchanges and determine if front-running has occurred. Your solution should be able to handle data from multiple exchanges, with the expectation…Process Scheduling: using C or C++ Design and implement four different schedulers. These include: First-Come, First-Serve (FCFS), Shortest Job First non-preemptive (SJFnp), Shortest Job First preemptive (SJFp), and Predicted Shortest Job First non-preemptive (PSJFnp). Afterwards, you should undertake comparative performance experiments and write a report on how performance is impacted by the policy underlying each scheduling algorithm.Function cai (Io) should return companies whose shares are held by every investor i E I, It is defined recursively: • Base case:. cai(null) = null • Constructor case: cai ({i1, i2...in }) = {c| cE C and.

- Programming homework1) Simulated waiting queue in an Indian post office: In an Indian post office that not only distributes mail but also performs some financial activities like a savings bank, a lone postal worker attends to a single lineup of clients. As soon as a consumer enters the line, they are given a token # (serial number). After receiving assistance, the consumer exits the queue while the postal worker receives the token back. The employee could inquire as to how many consumers are still unattended at any one time.i) Put the system into practise using a suitable queue data structure, simulating the arrival and departure of consumers at random when the service is finished.q no 3: A certain grade of steel is graded according to the following condition: Hardness must be greater than 40 Carbon contents must be less than 0.8 Tensile strength must be greater than 5000 The grades are as follows: Grade is 10 if all the three conditions are met. Grade is 9 if conditions 1 and 2 are met. Grade is 8 if conditions 2 and 3 are met. Grade is 7 if conditions 1 and 3 are met. Grade is 6 if only one condition is met. Grade is 5 if none of the conditions are met. Write a C++ program which will require user to give values of hardness, carbon content and tensile strength of the steel under consideration then determine the grade of steel and outputs the grade of the steel.C++ Programming Problem: After Elon Musk decided to make a new business idea. He found a social network called "Friends.com". It has currently N registered users. Likewise in any social network many users can be friends. Elon Musk wants the world to be as super connected as possible, so he has this new way to suggest friendship to some pairs of users. He suggests user u to have a friendship with user v if they are not friends yet and there is a user w who is friends of both of them. Note that u, v and w are different users. Elon Musk is too busy with SpaceX these days, so he hired you to develop a C++ program to count out how many friendship suggestions he has to send over his social network "Friends.com".
