Quicksort is being applied to an array containing, in the given order, 5, 3, 8, 7, 2, 9, 1, 6, 4 Assume that the pivot selection strategy is to pick the first element in the array, and that the in-place (unstable) partitioning algorithm is used. For the first execution of the partition algorithm only, draw the array contents initially and immediately after each execution of the call to swap in this algorithm, identifying on your drawing which index location the variables leftmark and rightmark refer to
