Leetcode Solutions

Dynamic Programming Approach

  1. Initialize max_so_far and min_so_far to the first element of the array, and result to max_so_far.
  2. Iterate through the array starting from the second element.
  3. For each number, calculate the potential new max_so_far and min_so_far by considering the current number, the product of the current number and the previous max_so_far, and the product of the current number and the previous min_so_far.
  4. Update max_so_far with the maximum of these three values, and min_so_far with the minimum.
  5. Update result with the maximum of result and the new max_so_far.
  6. Return result as the largest product of any subarray.
