Problem地址:http://acm.zju.edu.cn/onlinejudge/showProblem.do?problemId=5520 根据题目的要求,需要算出所有连续子数组的the beauty的总和. 那么要求这个这个总和,刚开始最容易想到的就是这样: for( int i=1; i<=N; i++ ) { for( int j = 1; j<=i; j++ ) { ... //排除重复的数计算总和 } } 这样子的结果实际上是 Time Limit Exceeded 因此采取…

也是一道比赛时候没有写出来的题目,队友想到了解法不过最后匆匆忙忙没有 A 掉 What a pity... 题意:定义Beauty数是一个序列里所有不相同的数的和,求一个序列所有字序列的Beauty和 1 <= N <= 100000 解题思路:由于数据比较大,常规方法求字序列和肯定是行不通的,我们不妨这样想:因为要区别于不同的数 ,可以看成序列里的数是一个一个加进去的,每次加入一个数,统计前面序列里第一次出现新加入的这个数的位置,表达的不好, 举个例子: 1 2 3 定义dp(当前元素前面(…
