Leetcode Solutions

Divide and Conquer Approach

  1. Define a function f that takes an integer n and returns a beautiful array of length n.
  2. If n is 1, return the array [1] as the base case.
  3. Recursively call f to get a beautiful array for the first (n+1)/2 numbers (which will contain all the odd numbers up to n).
  4. Recursively call f to get a beautiful array for the first n/2 numbers (which will contain all the even numbers up to n).
  5. Map the first set of numbers to 1, 3, 5, ... by multiplying each number by 2 and subtracting 1.
  6. Map the second set of numbers to 2, 4, 6, ... by multiplying each number by 2.
  7. Concatenate the two mapped arrays to form the final beautiful array.
  8. Use memoization to store and reuse results of subproblems to improve efficiency.
