Collapse Problem #2 Complete the class Problem2, the program does the following: • The program prompts the user to enter an integer. • The program continues to prompt the user for more integers as long as the sum of all values entered is between 1 and 50. • If the sum of all values entered is NOT between 1 and 50, Java the program stops taking integers, then display the value of sum. Here are two sample outputs, your output should look exactly the same as follows: Enter an integer: 23 Enter an integer: 1 I Enter an integer: -2 Enter an integer: 19 Enter an integer: -25 Enter an integer: 4 Enter an integer: 9 Enter an integer: -20 Enter an integer: -5 Enter an integer: -12 AK -8 lacBook Air

Q1: Research Groups In response to popular demand, Dan’s established two research groups A and B composed of his n graduate students. Each of these students is a member of exactly one of the two groups at any given time. The students are numbered from 1 to n in some arbitrary order. To measure the success of his research groups, Dan assigns a citation score to each of them. Initially, both groups have citation score 0. Throughout the semester, events of the following two types happen: Student x publishes a paper in which they cite student y’s work (youcan assume all of the students have been around long enough to have prior research that can be cited). As a result, If x and y are in the same group, their group’s citation score increases by 1. If x and y are in different groups, y’s group’s citation score increases by 5. Dan changes student x’s group (from A to B or from B to A) to have them work on different projects. To assess the overall success of the research groups, Dan…

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.
