+The innermost loop, from startO to endO, adds to %[i] three times 1 and
 it is executed 10x10 times. Whereas the outermost loop, from startO to endO,
 executes 10 times the innermost loop and adds two times 2 to the register %[j].
 At the end of the loop, the register %[i] contains 300 and the register %[j] contains 40.
