Using java create an array of 250,000,000 random elements, and use different numbers of threads to compute the sum and compare the run times. The number of threads changes from 1 to 100. You can only try the numbers that are factors of 250,000,000 so each thread will compute the same portion of the array, this should be done using a loop. There should be a global variable "sum" which can be accessed by all threads. Each thread will add their result the sum.
