题目地址:https://leetcode-cn.com/problems/max-difference-you-can-get-from-changing-an-integer/题目描述给你一个整数 num 。你可以对它进行如下步骤恰好 两次 :选择一个数字 x (0 <= x <= 9). 选择另一个数字 y (0 <= y <= 9) 。数字 y 可以等于 x。 将num 中所有出现
The input array will only contain0and1. The length of input array is a positive integer and will not exceed 10,000 思路:count存储当前连续1的数量,max为最大连续1的数量,遍历数组,遇见0便取count与max的较大者,遇见1则将count加1。要注意最后末尾的1。

The naive solution is brute-force, which is O((mn)^2). In order to be more efficient, I tried something similar to Kadane's algorithm. The only difference is that here we have upper bound restriction K. First, How to find the max sum rectangle in 2D array? The naive way is O(N^...

A hash map uses a hash function to compute an index into an array of buckets or slots, from which the desired value can be found. Collision Resolution Separate Chaining: in separate chaining, each bucket is independent, and contains a list of entries for each index. The time for hash map...
