8. Algorithm Design: Iterative (13 points) An iterative strategy to move any and all zeroes in an array A of n numbers, n21, to the left end of the array: 1. Let leftp be a pointer to the leftmost index of A and rightp be a pointer to the rightmost index of A. 2. Move leftp right until leftp is pointing to a cell containing a non-zero number or leftp reaches the right end of A. 3. Move rightp left until rightp is pointing to a cell containing a zero or r reaches the left end of A. 4. If left and right are not equal or have not crossed (passed) each other, swap the numbers in cells pointed to by left and right and repeat 2-4. 5. If left and rightp are equal or have crossed (passed) each other then stop. The corresponding iterative algorithm is given in part below. Complete it. Move-zeroes-iterative(A: array [p..r] of number, r-p20) 1. leftp = p; rightp=r 2. repeat 3. swap(A[leftp), A[rightp]) 4. while leftpsr and 6. while rightpp and 8. until
