  1. Split the input expression into two parts, num1 and num2, using the '+' operator as the delimiter.
  2. Initialize variables to store the minimum result and the corresponding expression with parentheses.
  3. Iterate over all possible ways to split num1 and num2 into two parts each, a and b for num1, and c and d for num2.
  4. For each split, calculate the result of the expression as a * (b + c) * d, where a and d default to 1 if they are empty.
  5. If the calculated result is less than the current minimum, update the minimum result and the corresponding expression.
