릿코드 2073. Time Needed to Buy Tickets 코틀린

그냥 해당값 맨앞으로 빼주고 전체제거해도되고
큐써서 처리해도되고 상관없을듯

정답

class Solution {
    fun timeRequiredToBuy(tickets: IntArray, k: Int): Int {
        var ticketList = tickets.toMutableList()
        var res=0
        for (i in 0 until k){
            res+=1
            val temp = ticketList.removeAt(0) - 1
            if (temp>0){
                ticketList.add(temp)
            }
        }
        while (ticketList[0]!=0){
            if (ticketList[0]==1){
                res+=1
                return res
            }
            res+=ticketList.size
            ticketList=ticketList.map { it-1 }.filter { it>0 }.toMutableList()
        }
        return res
    }
