题目链接 题目要求: Given a triangle, find the minimum path sum from top to bottom. Each step you may move to adjacent numbers on the row below. For example, given the following triangle [ [], [,], [,,], [,,,] ] The minimum path sum from top to bottom is 11 (…

Remove Duplicates from Sorted Array 思路:两个指针,头指针在0,尾指针从1开始寻找,找到第一个不等于头指针值的数,覆盖掉头指针后面那个数,然后尾指针往后移. public int removeDuplicates(int[] nums) { if(nums.length <= 1) return nums.length; int i = 0; for(int j = 1; j < nums.length; j++){ if(nums[i] != nums[j…
