I cannot understand what is the objective here ,
please explain with detailed example.
Stock Span Challenge
We are given a list of prices of a stock for N number of days. We need to find stock span for each day. Span is defined as number of consecutive days before the given day where the price of stock was less than or equal to price at given day. For example, {100, 60,70,65, 80, 85} span for each day will be {1, 1, 2, 1, 4, 5}.
For first day span is always 1. In example, notice that on day 2, price of stock is 60 and there is no day prior to it where price was less than 60. Hence span for day 2 is 1 again. For day 3, price at day 2 (60) is less than 70, hence span for day 3 is 2. Similarly, for day 4 and day 5. Remember days should be consecutive, that’s why span for day 4 is 1 even though there was a day 2 where price was less than 65.
