Topic link MeaningThere are n numbers and q Q, and each query gives a positive integer k K, asking what number of K K is small in all numbers of n n numbers or combinations, and if not, output −1-1. Ideas:First, the N-n number of the different or linear base is constructed. Assuming that non 0 linear bases have a total of tot tot, the results of the first 1− (x−1) n (x-1) linear group, regardless of linear combination, are less than the X-X linear bas

calls the Resultset.next () method before the first row, allowing the cursor to point to a specific row of data and invoke the method to fetch the row's data. ResultSet since it is used to encapsulate execution results, the object provides a get method for getting data: Gets any type of data getObject (int index) GetObject (string columnName) Gets the data of the specified type , for example: getString (int index) getString (String columnName) ResultSet also provides a way to scroll the result
