Steps: 9
Step 1: Identify the friends: A, B, C, D, and E.
Step 2: Understand the first clue: A is to the left of B. This means A comes before B in the order.
Step 3: Understand the second clue: A is to the right of C. This means C comes before A in the order.
Step 4: Combine the first two clues: Since C is before A and A is before B, we have C, A, B in that order so far.
