Sum Consecutive Identical Digits

Given a string of digits, repeatedly sum any consecutive identical digits until there are no more consecutive duplicates. For example: Input: 99823

• 99 becomes 18 → 18823
• 88 becomes 16 → 11623
• 11 becomes 2 → 2623 Now there are no more consecutive identical digits, so output the final result: 2623. Function Description Complete the function sumConsecutiveIdenticalDigits in the editor. sumConsecutiveIdenticalDigits has the following parameter:
• String digits: a string of digits Returns String: the final string after summing all consecutive identical digits
