range

问题 I am trying to calculate average monthly value of premiums for each POLICY_ID in monthly basis as shown below. When a customer updates his/her yearly payment frequency to a value different than 12, I need to manually calculate the average monthly value for the PREMIUM. How can I achieve the values shown in MONTHLY _PREMIUM_DESIRED? Thanks in advance. Note: Oracle version 12c What I've tried: SELECT T.*, SUM(PREMIUM) OVER(PARTITION BY T.POLICY_ID ORDER BY T.POLICY_ID, T.PAYMENT_DATE ROWS

问题 For example, if I want to find the smallest element of a collection, but only the smallest even element, I'd like to call ranges::min_element with a filtered range like so: using ranges::views::filter; using ranges::min_element; std::vector<int> vals{1,2,3,4,5}; auto minVal = min_element(vals | filter([](int next){return next % 2 == 0;})); How do I check if the returned range is empty, and if not, access the value? The same applies to other range algorithms like ranges::find , ranges::find_if

问题 This question already has answers here : What does iota of std::iota stand for? (5 answers) Closed 6 years ago . C++11 introduced a function called iota. Which "Assigns to every element in the range [first,last) successive values of val, as if incremented with ++val after each element is written." Can someone explain what "iota" means here though? I looked up "iota" and it seems to have nothing to do with generating a range. 回答1: Quoting this non-authoritative, but nonetheless correct, wiki:

问题 I'm working with bokeh to generate stock data, whereby the user selects a tickername and start/end dates to generate a graph. However, when selecting certain stocks, the y axis becomes distorted (See my previous question: Bokeh plot becomes distorted when certain stocks are inputted). I've tried to mitigate this by manually setting the y range as the min and max values of a stock upon selection, however, the new range does not update and the y axis does not change. How can I fix this issue?
