Write a function makeArray that takes in an array of integers itself and the length of that array (so for the example above, the first parameter would be the array storing 10, 20, 200 and 30 and the second parameter would have a value of 4 and allocates space for an array of arrays where each of the individual arrays have the lengths specified by the values of the input array. Before returning a pointer to the array of arrays, the function should store O in every element of every array allocated.

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system.currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system.currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system.currenttimemillis() just after the end of the algorithm as the elapsed time.
