When I finished reading this problem,I thought I could solve it by scanning every single subarray in the array,and the time complexity is cubic.Every subarray could be the eventual one whose sum is the largest,so I did make a conclusion that the best…
QUESTION: Write a class DominoChecker that has a method called addBox(int[]) that takes a box of five dominoes, described as a list of 10 integers (explained after), adds it to a collection, and returns true if a box with the same dominoes was alread…
题目: 删除排序数组中的重复数字 给定一个排序数组,在原数组中删除重复出现的数字,使得每个元素只出现一次,并且返回新的数组的长度. 不要使用额外的数组空间,必须在原地没有额外空间的条件下完成. 样例 给出数组A =[1,1,2],你的函数应该返回长度2,此时A=[1,2]. 解题: 用Python直接搞 Python程序: class Solution: """ @param A: a list of integers @return an integer "&q…
Given a sorted array, remove the duplicates in-place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra memory. Ex…
题目: 给定一个排序数组,移除重复出现的元素,保证每个元素最终在数组中只出现一次.返回新数组的长度length; 要求:不能分配额外的一个数组使用,必须使用原地排序的思想,且空间复杂度为O(1) 举例: Given input array nums = [1,1,2], Your function should return length = 2, with the first two elements of nums being 1 and 2 respectively. It doesn't…
[问题描写叙述] Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array. Note: You may assume that nums1 has enough space (size that is greater or equal to m + n) to hold additional elements from nums2. The number of elem…
