今天毕业五年了,一直忙于工作和享受,自从当年找完工作后就一直没有再刷过题,作为搬砖的码农,觉得还是应该养成长期刷题的习惯坚持下去。之前坚持了每天被一会单词,如今雅思一本也快看完了,从今天开始准备在保证每周一题的最低基础上坚持下去,不为别的,主要是想多动脑,刷个几十年坚持下去,应该可以预防老年痴呆。。。
题目:
滑动窗口的解法:注意蛋疼的int[][]返回值类型,十分蛋疼
public class Solution
{public int[][] FindContinuousSequence(int target){List<int[]> res = new List<int[]>();int leftIndex = 1;int rightIndex = 2;int loopNum = target/2 + 1;target *= 2; while(rightIndex <= loopNum){int sum = (leftIndex + rightIndex) * (rightIndex - leftIndex + 1);if(sum < target){rightIndex++;}else if(sum > target){leftIndex++;}else{List<int> seq = new List<int>();for(int i = 0; i < rightIndex - leftIndex + 1; i++){seq.Add(leftIndex + i);}res.Add(seq.ToArray());leftIndex++;rightIndex = leftIndex + 1;} }return res.ToArray();}
