3. Using Loop andStringBuilder Using aforloop with aStringBuilderprovides a straightforward approach to removing digits from aString. This method involves iterating over eachCharacterin theString, checking if it’s a digit, and then appending non-digitCharactersto aStringBuilder: @TestvoidwhenUsingFor...
Calculate the number of invalid parentheses of the original string. Iterate through the string. Remove each character and DFS if the number of invalid parentheses decreases. This solution is based on the fact that if we're on the right path to the optimal string, the number of invalid parenth...
