나의 풀이

import java.util.Arrays;

class Solution {
    public int solution(int[] array, int n) {
        int answer = 0;
        int diff = 2147000;
        Arrays.sort(array);
        for (int num : array){
            if (Math.abs(num - n) < diff) {
                diff = Math.abs(num - n);
                answer = num;
            }
        }
        return answer;
    }
}

class Solution {
    public int solution(int[] array, int n) {
        return Math.min(array[Arrays.stream(array).map(operand -> Math.abs(n - operand)).boxed().collect(Collectors.toList()).indexOf(Arrays.stream(array).map(operand -> Math.abs(n - operand)).min().orElse(0))], array[Arrays.stream(array).map(operand -> Math.abs(n - operand)).boxed().collect(Collectors.toList()).lastIndexOf(Arrays.stream(array).map(operand -> Math.abs(n - operand)).min().orElse(0))]);
    }
}

미쳤다.. 그냥
