total과 target을 === 연산자로도 비교할 수 있을 것 같습니다! ==연산자를 사용한 이유가 궁금합니다

알고리즘 문제를 풀때는 엄격한 비교가 방해될때가 있어서 그렇게 하는 편인데.. 안좋은 습관일까요

dp 배열을 사용해 문제를 풀이해주셨군요! 배열을 사용하지 않고 변수만 사용해서 공간복잡도를 줄이는 방법도 있습니다. 다음에 한 번 고려해보면 좋을 것 같습니다.

isAlphaNumeric() 이라는 함수를 정의하니 코드가 분리돼서 보기 편했습니다. 아스키코드로 풀이를 하셨네요! 정규표현식을 사용해서도 풀이할 수 있을 거 같습니다. 다음에 고려해보시면 좋을 것 같습니다.
