  1. Initialize a counter to keep track of the number of operations.
  2. While n is not equal to 1: a. If n is even, divide it by 2 using right shift operation. b. If n is odd and not equal to 3, check the second least significant bit: i. If it is 0 (binary ends with '01'), decrement n. ii. If it is 1 (binary ends with '11'), increment n. c. If n is 3, decrement n. d. Increment the counter.
