解题思路

• 直接从1开始遍历到$10^n-1$

AC代码

class Solution {
    public int[] printNumbers(int n) {
        int[] ans = new int[(int) Math.pow(10, n) - 1];
        for (int i = 1; i < Math.pow(10, n); i++) {
            ans[i - 1] = i;
        }
        return ans;
    }
}

本地测试代码

package com.company;

import java.util.Arrays;

public class Solution_1661 {
    public static int[] printNumbers(int n) {
        int[] ans = new int[(int) Math.pow(10, n) - 1];
        for (int i = 1; i < Math.pow(10, n); i++) {
            ans[i - 1] = i;
        }
        return ans;
    }

    public static void main(String[] args) {
        System.out.println(Arrays.toString(printNumbers(1)));
    }
}
