Given a list of sorted characters letters containing only lowercase letters, and given a target letter target, find the smallest element in the list that is larger than the given target. Letters also wrap around. For example, if the target is target…

题目要求 Given an array A of integers, for each integer A[i] we may choose any x with -K <= x <= K, and add x to A[i]. After this process, we have some array B. Return the smallest possible difference between the maximum value of B and the minimum value…

Given an m * n matrix M initialized with all 0's and several update operations. Operations are represented by a 2D array, and each operation is represented by an array with two positive integers a and b, which means M[i][j] should be added by one for…

题目如下: 解题思路:简单的不能再简单的题目了,对于任意一个A[i]来说,其可能的最小的最大值是A[i]-K,最大的最小值是A[i]+K.遍历数组,求出所有元素中最大的最小值和最小的最大值,两者之差(小于零则取零)就是答案. 代码如下: class Solution(object): def smallestRangeI(self, A, K): """ :type A: List[int] :type K: int :rtype: int """…

Given a list of strings words representing an English Dictionary, find the longest word in words that can be built one character at a time by other words in words. If there is more than one possible answer, return the longest word with the smallest l…

We want to use quad trees to store an N x N boolean grid. Each cell in the grid can only be true or false. The root node represents the whole grid. For each node, it will be subdivided into four children nodes until the values in the region it repres…
