sum记录当前的累加和,depth记录当前数组中元素数目,tem记录当前存储的元素(dfs的路径),ans最终答案; 出口:深度depth达到k,函数返回。当sum == n时,将tem加入ans; 递归:for(int i = (tem.size() == 0 ? 1 : tem.back() + 1); i <= 9; i++),将i作为下一个元素,再次进行dfs(sum + i, depth...
前缀和(Prefix Sum) 对于一些算法问题直接求解的思路可能计算量比较大,可以思考利用预处理一组特定的中间数据来进求解。类比就如同初中解一些几何题通过几条辅助线的解法,如果回顾学习辅助线的画法,往往先了解常见的画法;对于算法,前缀和就是“常见的辅助线画法”。
Java Python Array-2 sum13 Return the sum of the numbers in the array, returning 0 for an empty array. Except the number 13 is very unlucky, so it does not count and numbers that come immediately after a 13 also do not count.
