<div style="font-family: monospace, Consolas, 'Courier New', monospace; font-size: 14px; white-space: pre;">여기서 train_test_split와 DecisionTreeClassifier의 random_state는 어떻게 다른가요??</div>
<div style="font-family: monospace, Consolas, 'Courier New', monospace; font-size: 14px; white-space: pre;">그리고 DecisionTreeClassifier에서의 random_state를 변경하면 정확도도 동일해야 하는거 아닌가요?</div>
<div style="font-family: monospace, Consolas, 'Courier New', monospace; font-size: 14px; white-space: pre;">13보다 작은 수를 입력했을 때는 정확도가 일정한데 13보다 큰 수를 입력하면 왜 정확도가 달라지는지 잘 모르겠습니다.</div>
