릿코드 1422. Maximum Score After Splitting a String 코틀린

그냥 스트링 인덱스로 for 돌려서,왼쪽은 인덱스-sum값,오른쪽은 sum값을 더해서 maxRes랑 비교



정답

import kotlin.math.max

class Solution {
    fun maxScore(s: String): Int {
        var maxRes=0
        var leftValue=0
        var rightValue=s.sumOf { it.digitToInt() }
        for (i in s.indices){
            if (i==s.length-1){
                break
            }
            leftValue+=s[i].digitToInt()
            rightValue-=s[i].digitToInt()

            maxRes= max(maxRes,((i+1)-leftValue+rightValue))
        }

        return maxRes
    }
}
