4-SUM : Given N distinct integers, how many quadruples add to exactly zero The assignment is to design an Algorithm for a 4-Sum problem and use it to create a Java program to run experiments. The program can be implemented in a program with two methods: solution methods in solving the 4-Sum problem and a main method to be able to take input and carry out the execution to answer how many quadruples are there give the list of numbers from input. Run experiments with 250,500,1000,2000,4000,8000 integers respectively as input, and measure the total execution time for each different input size. Create an assignment report to include a table of execution times for each input size resulted from running the 4-sum program. Establish a hypothesis for execution time modeling using power law. Solve the power law and find the function for th model. Verify if your model is valid by solving the problem with input size of 16,000 . Also compute the execution time for size of 16,000 using the function from hypothesis modeling to predict the length of execution. Comments on the validation process about the result
