Leetcode 368. Largest Divisible Subset

Algorithm
1. Sort the input array in ascending order to ensure that if a is divisible by b, an appears after b.

2. Create a dp array where dp[i] represents the size of the largest divisible subset that ends at index i.


3. For each element at index r from left to right, check all previous elements at indices less than r. If nums[r] is divisible by nums[l], update dp[r] as the maximum of its current value and dp[l] plus 1.

4. Backtrack from the end
