[BOJ/Java] 1436 영화감독 숌 contains 함수를 생각 못하고 while (totalCnt != n) { str = Integer.toString(num); for (i = 0; i < str.length() - 2; i++) { if (str.substring(i, i + 3).equals("666")) { totalCnt++; break; } } num++; } 이런 식으로 매 숫자마다 String을 생성하고 또 substring으로 생성하고, 해당 String의 index를 생각해서 했더니 메모리 초과가 발생했다. String이 너무 많아지니 당연히 메모리 초과가 발생하는 건데 메모리도 생각하며 짜도록 해야겠다. 정답 코드 import java.io.BufferedReader; import java.io.InputStream.. 2022. 2. 13.
