Can you solve this real interview question? Maximum Alternating Subsequence Sum - The alternating sum of a 0-indexed array is defined as the sum of the elements at even indices minus the sum of the elements at odd indices. * For example, the alternatin

接着遍历这个前缀和的数组,用hashmap记录<prefix sum, i> -每个不同的前缀和和他们出现的位置。如果此时发现nums[i] - k在hashmap中,则res = Math.max(res, i - map.get(nums[i] - k))。这个例子里面,K = 3,前缀和跑到3的时候,发现3-3 = 0在hashmap里出现过,此时结算出来的res = 4。当然,...

理解正增益的概念:核心就是利用sum记录累加和,一旦sum<0,表明之前的元素对后面的元素来说不会有增益的效果,故需重置sum=0。具体可参考这篇文章@&再见萤火虫&【LeetCode_Array_53. Maximum Subarray (C)】 需要临时的first_和last_来记录first和last(最长子序列的始末元素),并在合适的时候对其进...
