Leetcode Problem 1806. Minimum Number of Operations to Reinitialize a Permutation

1806. Minimum Number of Operations to Reinitialize a Permutation

Leetcode Solutions

Simulation of a Single Index

  1. Initialize res to 0, which will count the number of operations.
  2. Initialize i to 1, which represents the index we are tracking (since the permutation starts at 0).
  3. Use a loop to simulate the operation until i returns to 1: a. If i is less than n / 2, then i becomes i * 2. b. If i is greater than or equal to n / 2, then i becomes (i - n / 2) * 2 + 1. c. Increment res by 1 after each simulation step.
  4. The loop terminates when i returns to 1, and res is the result.
