LintCode 407: Plus One 题目描述 给定一个非负数,表示一个数字数组,在该数的基础上+1,返回一个新的数组. 该数字按照位权大小进行排列,位权最大的数在列表的最前面. 样例 给定 [1,2,3] 表示 123, 返回 [1,2,4]. 给定 [9,9,9] 表示 999, 返回 [1,0,0,0]. Sat Feb 26 2017 思路 本题没什么特殊的地方,就是让你手算一个加一运算,用加法器的思想即可. 代码 // 加一 vector<int> plusOne(vecto…

题目描述: 分析:由样例可以知道,当数组的每一个数字都是9时,加一会产生一个最高位的数字1,所以先判断这个数组的每一位是否都是9,如果是,那么新数组的大小是原数组大小加一,否则新数组的大小等于原数组的大小.数字加一,其实也就是数组的最后一个数字加一,但是加一的时候可能会产生进位(9+1=10:就产生了向前一位的进位),用一个数字k表示向前一位的进位(k=1:向前产生了进位,k=0:没有产生进位)由此加到原数组的第一个数字为止,如果最高位也就是原数组的第一位也产生了进位,那么将新数组的第一位置为1…

题目: 加一 给定一个非负数,表示一个数字数组,在该数的基础上+1,返回一个新的数组. 该数字按照大小进行排列,最大的数在列表的最前面. 样例 给定 [1,2,3] 表示 123, 返回 [1,2,4]. 给定 [9,9,9] 表示 999, 返回 [1,0,0,0]. 解题: 好像只有这样搞,对应进位的时候,要新定义个数组 Java程序: public class Solution { /** * @param digits a number represented as an array o…
