Master the Construct the Lexicographically Largest Valid Sequence LeetCode problem with undetectable real-time assistance. Get instant solutions and explanations during your coding interviews.
Phantom Code generates complete solutions and debugging hints that you can use while explaining your approach, so you stay calm and in control.
Given an integer n, find a sequence with elements in the range [1, n] that satisfies all of the following: The distance between two numbers on the sequence, a[i] and a[j], is the absolute difference of their indices, |j - i|. Return the lexicographically largest sequence. It is guaranteed that under the given constraints, there is always a solution. A sequence a is lexicographically larger than a sequence b (of the same length) if in the first position where a and b differ, sequence a has a number greater than the corresponding number in b. For example, [0,1,9,0] is lexicographically larger than [0,1,5,6] because the first position they differ is at the third number, and 9 is greater than 5.
