You are given an integer n. A 0-indexed integer array nums of length n + 1 is generated in the following way:

\n\n\n\n

Return the maximum integer in the array nums​​​.

\n\n

 

\n

Example 1:

\n\n
\nInput: n = 7\nOutput: 3\nExplanation: According to the given rules:\n  nums[0] = 0\n  nums[1] = 1\n  nums[(1 * 2) = 2] = nums[1] = 1\n  nums[(1 * 2) + 1 = 3] = nums[1] + nums[2] = 1 + 1 = 2\n  nums[(2 * 2) = 4] = nums[2] = 1\n  nums[(2 * 2) + 1 = 5] = nums[2] + nums[3] = 1 + 2 = 3\n  nums[(3 * 2) = 6] = nums[3] = 2\n  nums[(3 * 2) + 1 = 7] = nums[3] + nums[4] = 2 + 1 = 3\nHence, nums = [0,1,1,2,1,3,2,3], and the maximum is max(0,1,1,2,1,3,2,3) = 3.\n
\n\n

Example 2:

\n\n
\nInput: n = 2\nOutput: 1\nExplanation: According to the given rules, nums = [0,1,1]. The maximum is max(0,1,1) = 1.\n
\n\n

Example 3:

\n\n
\nInput: n = 3\nOutput: 2\nExplanation: According to the given rules, nums = [0,1,1,2]. The maximum is max(0,1,1,2) = 2.\n
