Step 2: Repeat steps a & b until the current index is > 0. Add fenArr [idx] to the sum. Go to the parent of fenTree [idx]. The parent can be reached by truncating the last set bit from the current index, i.e., idx = idx - (idx & (-idx)) Step 3: Return the sum. shape interiors pontoon platform plans
