Implement a Java test drive following this step: (1) declare and initialize an int N to 10 (change to 1000000 later) declare and new an array of n strings, say, x, which simulates Facebook's user names (2) initialize each string element by using x[i] String.valueof(((int) (Math.random()*100000000))); (just use some random digits to pretend to be username) (3) set a target="345461223" (later on change to x[N/2]) (4) write a loop to perform linear search for the target in x (5) surround the loop using long t0 = System.currentTimeMillis(); //loop long ti = System.currentTimeMillis(); (6) write codes to print out the index position where the target is located at or -1 if target is not present. Print out ti-to as well, which is the time spent on the search (7) modify the your codes of creating x[i] so that x[i] will be sorted increasingly. (8) Run the linear search again. (9) get the BinarySearch.java from BB, modify it to deal with string array. (change "w" to ".equals()", xay to m.compareTo(Y)
