Assume a method already has code that constructs and populates an int array and declares a few helpful variables for you to use. This is what you have so far: int iNums[] = {3, 18, 4, 1, 9, 13, 7};, int iTemp;, and int iSub; With that start, write a block of code that left-shifts the array, moving each value one position to the left, with the original first element moving to the end of the array. It should take you 6 lines of code, including the lines with just braces. There is no output; don't add more to this than asked.
