题意: 给你一个有n个单词的单词串S,对这n个单词进行排列组合形成新的一个单词串T,如果在S中任意某个单词所在位置,和这个单词在T中所在位置之差的绝对值小于等于1,那么就说S和T串相等 让你求S一共有多少与之相等的串 题解: 刚开始以为规律就是斐波那契,交了一发wa了 首先如果n==1时,dp[1]=0 用f[i]表示S串的第i个单词,则如果对于n+1的S串,如果f[n]==f[n+1],那么dp[n]==dp[n+1] 如果对于n+1的S串,如果f[n]!=f[n+1],那么dp[n+1]=d…

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…
