When we query the index state, we usually use the User_indexes table, which has a column (Clustering_factor clustering factor), here simply describes the meaning of the next cluster factor, you know that the data in the data table is a disordered existence in the library, When we are retrieving the data, looking up is very resource-intensive, so we need to create indexes for tables, the role of the index is

Test instructions: Give you A, B, let a^b all the factors and modulo 9901Idea: A can be split into the product of the element factor: a = p1^x1 * p2^x2 *...* PN^XNThen a^b = p1^ (b*x1) * p2^ (B*X2) *...* pn^ (B*XN)So a^b all the vegetarian factors and is(p1^0 + p1^1 + p1^2 + ... + p1^ (b*x1)) * (p2^0 + p2^1 + ... + p2^ (b*x2)) * ... * (pn^0 + pn^1 + ... + pn^ (B*XN))It can be seen that each parenthesis is geometric series, but do not use the geometric

NetScaler OTP Application ScenarioNetScaler OTP (one time password) is a two-factor ID card that uses the username password + 6-bit token authentication code to complete the identity authentication. In the previous two-factor solution, Netscalergateway needed to be integrated with a third-party RADIUS server for two-factor authentication. For customers, the cost
