Step 3 of an input is : 36 window 45 96 86 ultra book queen
How many more steps will be required to complete the rearrangement?
Answer: A
Correct answer: Three
The placement order for this line is 36, window, 45, ultra, 86, queen, with 96 and book left over. Step 3 has 36, window and 45 in place, so three moves remain: ultra to position four, then 86 to position five, then queen to position six. After that only 96 and book are left and the arrangement is complete, so three more steps are needed.
