1.这个题不难,关键在于把题目意思理解好了.这个题问的不清楚.要求return new length,很容易晕掉.其实就是return 有多少个单独的数. import java.util.Arrays; /* * Question: Given a sorted array,remove the duplicates in place such that each element * appear only once and return the new length * * Do not a…

[ 12 | 2434 | 23 | 1 | 654 | 222 | 56 | 100000 ] Then the output should be: [ 1 | 100000 | 12 | 222 | 23 | 2434 | 56 | 654 ] 建立自己的comparator: Comparator<Integer> intLexCompare = new Comparator<Integer>() { int compareTo( Integer x, Integer y)…

参考:http://stackoverflow.com/questions/34584416/nested-loops-with-arrays You are going to be given an array of integers. Your job is to take that array and find an index N where the sum of the integers to the left of N is equal to the sum of the integ…

414. Third Maximum Number 给一个非空的整数数组,找到这个数组中第三大的值,如果不存在,那么返回最大的值.要求时间复杂度为o(n) 例如: Example 1: Input: [3, 2, 1] Output: 1 Explanation: The third maximum is 1. Example 2: Input: [1, 2] Output: 2 Explanation: The third maximum does not exist, so the maxi…

Given a sorted positive integer array nums and an integer n, add/patch elements to the array such that any number in range [1, n] inclusive can be formed by the sum of some elements in the array. Return the minimum number of patches required. Example…

In a given integer array A, we must move every element of A to either list B or list C. (B and C initially start empty.) Return true if and only if after such a move, it is possible that the average value of B is equal to the average value of C, and…

Given a non-empty integer array, find the minimum number of moves required to make all array elements equal, where a move is incrementing a selected element by 1 or decrementing a selected element by 1. You may assume the array's length is at most 10…

Given a non-empty integer array of size n, find the minimum number of moves required to make all array elements equal, where a move is incrementing n - 1 elements by 1. Example: Input: [1,2,3] Output: 3 Explanation: Only three moves are needed (remem…
