Given a non-negative number represented as an array of digits, plus one to the number. The digits are stored such that the most significant digit is at the head of the list. 题解: 这道题就是实现题。 先对原数组进行处理。从数组最后一位开始往前检查,如果当前数字是<9的,说明你加1无需进位...
publicint[] plusOne(int[] digits) {if(digits ==null|| digits.length == 0)returnnull;intlen =digits.length;intcarry = 0;//进位,只借用一个变量,不需要数组for(inti = len - 1; i >= 0; i--){if(i == len - 1){ carry= (digits[i] + 1 ) / 10;//进位digits[i] = (digits[...
如果越界的话,说明原数全是9,那就要建个新数组存放结果。 注意 System.arraycopy(src, 0, dst, 0, length)可以用来高效拷贝数组 代码 public class Solution { public int[] plusOne(int[] digits) { int i = digits.length - 1; // 从后向前把所有连续9置0,直到不是9 while(i >= 0 && digits[...

leetcode 66. Plus One Given anon-emptyarray of digits representing a non-negative integer, plus one to the integer. The digits are stored such that the most significant digit is at the head of the list, and each element in the array contain a single digit....
// 错误答案 var plusOne = function(digits) { let str = digits.join('') // 将数组元素拼接成字符串 let newNum = Number(str) + 1 // 执行 加1的操作 let newArr = newNum.toString().split('') // 将数字转成数组 return newArr.map(Number) // 将数组中的字符串元素转成数字并返回结果...
1、如果第一次做LeetCode，你可以按照难度来做。我按照题目的难度和面试出现的频率打了分，1是最低分，5是最高分。你可以按照难度排序，从最简单的做起，逐渐提高难度。2、如果你有一段时间没有做，而LeetCode加了新题，你只想做新题怎么办？你可以去我的那个网站，上边的题目是按照时间顺序排好...
