자꾸 시간초과가 나서 readline 추가 import sys input = sys.stdin.readline n = int(input()) hw = [] final_score = 0 idx = 0 for _ in range(n): line = list(map(int,input().split())) if line[0]==1: if line[2]-1==0: final_score += line[1] else: hw.append([line[1],line[2]-1]) idx += 1 else: if len(hw)>0: hw[idx-1][1] -= 1 if hw[idx-1][1]==0: score, time = hw.pop() final_score+=score idx -= 1 print(final_score)
