We want to make sure we maintain the deque such that the first element in deque is always the index to the max element in sliding window. How? every time before we append a new index j into deque, we first check from the beginning, pop index out of range; then we check from the e...
允许输入序列元素有重的变种(见LeetCode 81.选择排序数组的指定值):与元素不可重的实现一样,只不过多了一步首尾元素一样时的去重操作。 View Code 2、升序序列循环左移(右移也可,实现完全一样;可以是0位,此时是有序序列;元素不可重)若干位后查找最值(见LeetCode153.旋转排序数组的最小值): (总结:利用局...
