코딩테스트 연습 - 다리를 지나는 트럭

 

sum을썼었는데따로가볍게계산하게끔했음

def solution(bridge_length, weight, truck_weights):
    bridge=[]
    for i in range(bridge_length):
        bridge.append(0)
    w=0
    answer = 0
    bridge_weight=0
    while(truck_weights):
        answer+=1
        w-=bridge.pop()
        bridge= [0]+bridge
        if w+truck_weights[0] <= weight:
            bridge[0]=truck_weights.pop(0)
            w+=bridge[0]
    return answer+bridge_length
