题目如下: 解题思路:和[leetcode]84. Largest Rectangle in Histogram的核心是一样的,都是要找出当前元素之前第一个大于自己的元素. 代码如下: class StockSpanner(object): def __init__(self): self.cl = [] self.vl = [] def next(self, price): """ :type price: int :rtype: int """…

Span 指这个元素之前连续的小于这个元素的值有多少个 原理: 维护递减栈 这个栈内的元素是递减的序列 新到一个元素x 依次出栈比x小的(也就是这个元素的Span) 这种问题的关键在于 新来的元素如果比前一个元素小 那么答案是1 如果比前一个元素大 ( 那么前一个元素在之后就完全没有用了, 所以可以出栈, 使用现有的元素进行意义的记录 ) 相关题目 Unique Letter String Sum of Subsequence Widths 907 907是求一个双向的Span 但是有一个重复元…

ES基于Lucene开发,因此也继承了Lucene的一些多样化的查询,比如本篇说的Span Query跨度查询,就是基于Lucene中的SpanTermQuery以及其他的Query封装出的DSL,接下来就看一下这些DSL都如何使用吧! 更多翻译参考:Elasticsearch知识汇总 span_term查询 这个查询如果单独使用,效果跟term查询差不多,但是一般还是用于其他的span查询的子查询. 用法也很简单,只需要指定查询的字段即可: { "span_term" : { &qu…

编写一个 StockSpanner 类,它收集某些股票的每日报价,并返回该股票当日价格的跨度. 今天股票价格的跨度被定义为股票价格小于或等于今天价格的最大连续日数(从今天开始往回数,包括今天). 例如,如果未来7天股票的价格是 [100, 80, 60, 70, 60, 75, 85],那么股票跨度将是 [1, 1, 1, 2, 1, 4, 6]. 调用 StockSpanner.next(int price) 时,将有 1 <= price <= 10^5. 每个测试用例最多可以调用 100…
