TODO 0901. Online Stock Span medium
Design an algorithm that collects daily price quotes for some stock and returns the span of that stock's price for the current day.
The span of the stock's price in one day is the maximum number of consecutive days (starting from that day and going backward) for which the stock price was less than or equal to the price of that day.
- For example, if the prices of the stock in the last four days is
[7,2,1,2]and the price of the stock today is2, then the span of today is4because starting from today, the price of the stock was less than or equal2for4consecutive days. - Also, if the prices of the stock in the last four days is
[7,34,1,2]and the price of the stock today is8, then the span of today is3because starting from today, the price of the stock was less than or equal8for3consecutive days.
Implement the StockSpanner class:
StockSpanner()Initializes the object of the class.int next(int price)Returns the span of the stock's price given that today's price isprice.
Example 1:
Input
["StockSpanner", "next", "next", "next", "next", "next", "next", "next"]
[[], [100], [80], [60], [70], [60], [75], [85]]
Output
[null, 1, 1, 1, 2, 1, 4, 6]
Explanation
StockSpanner stockSpanner = new StockSpanner();
stockSpanner.next(100); // return 1
stockSpanner.next(80); // return 1
stockSpanner.next(60); // return 1
stockSpanner.next(70); // return 2
stockSpanner.next(60); // return 1
stockSpanner.next(75); // return 4, because the last 4 prices (including today's price of 75) were less than or equal to today's price.
stockSpanner.next(85); // return 6Constraints:
1 <= price <= 10^{5}- At most
10^{4}calls will be made tonext.
