How can i understand from the invariant that l is the correct value to be return

Question

How can i understand from the invariant that l is the correct value to be returned and how the initialisation of l=low; and h=high; establish the invariant? /* invariant * low <= l <= h <= high * In region for indexes i with low <= i < end: * elements are as originally, but rearranged. * if i < l then arr[i] < x * if i >= h then arr[i] >= x * Elements outside region are unchanged. */ private static int partition( int[] arr, int low, int high, int x) { int l = low; int h = high; while (l< x) { l =l +1; } else { int x = arr[l]; arr[l] = arr[h-1]; arr[h-1] = x h = h-1; } } return l; }
