[프로그래머스/javascript] 다리를 지나는 트럭 (좀 더 효율적으로 다시풀기)

function solution(bridge_length, weight, truck_weights){
    //다리건너는데 필요한 시간 -> bridge_length
    //즉 트럭하나가 건너려면 최소 bridge_length 시간은 있어야함
    let bridgeCrossing = [truck_weights[0]];
    let bridgeTimes = [0];
    let times = 1;
    let truckIdx = 1;
    let plus = false;
    while(bridgeCrossing.length>0){
        times++;
        bridgeTimes = bridgeTimes.map((el)=>el+1)
        if(bridgeTimes[0]>=bridge_length){
            bridgeCrossing.shift()
            bridgeTimes.shift()
        }
        let bridgeWeights = bridgeCrossing.reduce((prev,cur)=>prev+cur,0)
        if(truck_weights[truckIdx]&&bridgeWeights+truck_weights[truckIdx]<=weight){
            bridgeCrossing.push(truck_weights[truckIdx])
            bridgeTimes.push(0)
            truckIdx++
        }

    }
    return times
}

reduce와 map을 써서 시간복잡도가 높을것같다.

더 효율적인 방법이 있다.!
