题目大意:$n$列箱子,横向消除,一次可以把一行及以上的所有箱子消除,但是一次最多只可以消除$k$个,求最少用几次把箱子的高度变成一样 题解:贪心,求出比一个高度高的有几个箱子,消除即可 卡点:代码改了一次,结尾处理部分忘记改了   C++ Code: #include <cstdio> #include <algorithm> #define maxn 200010 inline int max(int a, int b) {return a > b ? a : b;} i…

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…

Given a non-empty array containing only positive integers, find if the array can be partitioned into two subsets such that the sum of elements in both subsets is equal. Note: Both the array size and each of the array element will not exceed 100. Exam…

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…

首先,==有很多限制,如Integer 类型的值在[-128,127] 期间,Integer 用 “==”是可以的(参考),超过范围则不行,那么使用equal则代替则完全ok public static void main(String[] args) { Long prop=4004L; Long prop1=4004l; Integer prop2=4004; Integer prop3=4004; if(prop2.equals(prop3)){ System.out.println("h…
