给定一个非负整数组成的非空数组,在该数的基础上加一,返回一个新的数组. 最高位数字存放在数组的首位, 数组中每个元素只存储一个数字. 你可以假设除了整数 0 之外,这个整数不会以零开头. 示例 1: 输入: [1,2,3] 输出: [1,2,4] 解释: 输入数组表示数字 123. 我一看,想居然有这么简单的题,把数组转成数字+1再转会数组不就行了 然而不通过,大概是发生了值超出数字上限之类的错误吧,果然还得思考 想了老半天 /** * @param {number[]} digits * @r…
加一 给定一个由整数组成的非空数组所表示的非负整数,在该数的基础上加一. 最高位数字存放在数组的首位, 数组中每个元素只存储一个数字. 你可以假设除了整数 0 之外,这个整数不会以零开头. Given a non-empty array of digits representing a non-negative integer, plus one to the integer. The digits are stored such that the most significant digit…
Given a non-negative number represented as a singly linked list of digits, plus one to the number. The digits are stored such that the most significant digit is at the head of the list. Example: Input: 1->2->3 Output: 1->2->4 这道题给了我们一个链表,用来模拟一…
Additive number is a positive integer whose digits can form additive sequence. A valid additive sequence should contain at least three numbers. Except for the first two numbers, each subsequent number in the sequence must be the sum of the preceding…
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. 将一个数字的每个位上的数字分别存到一个一维向量中,最高位在最开头,我们需要给这个数字加一,即在末尾数字加一,如果末尾数字是9,那么则会有进位问题,而如果…
Given a non-negative integer represented as a non-empty array of digits, plus one to the integer. You may assume the integer do not contain any leading zero, except the number 0 itself. The digits are stored such that the most significant digit is at…
In a 2D grid from (0, 0) to (N-1, N-1), every cell contains a 1, except those cells in the given list mines which are 0. What is the largest axis-aligned plus sign of 1s contained in the grid? Return the order of the plus sign. If there is none, retu…
Given a set of keywords words and a string S, make all appearances of all keywords in S bold. Any letters between <b> and </b> tags become bold. The returned string should use the least number of tags possible, and of course the tags should fo…
Given a nested list of integers, return the sum of all integers in the list weighted by their depth. Each element is either an integer, or a list -- whose elements may also be integers or other lists. Different from the [leetcode]339. Nested List Wei…
