738. 单调递增的数字 给定一个非负整数 N,找出小于或等于 N 的最大的整数,同时这个整数需要满足其各个位数上的数字是单调递增. (当且仅当每个相邻位数上的数字 x 和 y 满足 x <= y 时,我们称这个整数是单调递增的.) 示例 1: 输入: N = 10 输出: 9 示例 2: 输入: N = 1234 输出: 1234 示例 3: 输入: N = 332 输出: 299 说明: N 是在 [0, 10^9] 范围内的一个整数. class Solution { public int…
738. 单调递增的数字 知识点:字符串:贪心 题目描述 给定一个非负整数 N,找出小于或等于 N 的最大的整数,同时这个整数需要满足其各个位数上的数字是单调递增. (当且仅当每个相邻位数上的数字 x 和 y 满足 x <= y 时,我们称这个整数是单调递增的.) 示例 输入: N = 10 输出: 9 输入: N = 1234 输出: 1234 输入: N = 332 输出: 299 解法一:贪心 想一下这个过程,如果比前一位大的话那就可以不用动直接返回:如果比前一位小的话例如98,应该怎么做…
Given a non-negative integer N, find the largest number that is less than or equal to Nwith monotone increasing digits. (Recall that an integer has monotone increasing digits if and only if each pair of adjacent digits x and y satisfy x <= y.) Exampl…

A string of '0's and '1's is monotone increasing if it consists of some number of '0's (possibly 0), followed by some number of '1's (also possibly 0.) We are given a string S of '0's and '1's, and we may flip any '0' to a '1' or a '1' to a '0'. Retu…
Given an integer array, your task is to find all the different possible increasing subsequences of the given array, and the length of an increasing subsequence should be at least 2 . Example: Input: [4, 6, 7, 7] Output: [[4, 6], [4, 7], [4, 6, 7], [4…
