Complexity Analysis
Determine which substring ('ab' or 'ba') has a higher score and should be removed first.
Initialize a stack to keep track of characters.
Iterate through the string character by character.
For each character, check if the top of the stack and the current character form the higher-scoring substring.
If they do, pop the top of the stack and increment the score by the higher value.
If they don't, push the current character onto the stack.
After the first pass, repeat steps 3-6 for the lower-scoring substring using the modified string (stack content).
Return the total score.
