You may have heard that no two snowflakes are alike. your task is to write a program to determine whether this is really true. your program will read information about a collection of snowflakes, and search for a pair that may be identical. each snowflake
Study the hash Table:Each snowflake has its own 6 arm values, and if two snowflakes start at the same or a different position clockwise or counterclockwise, then the two snowflakes are equal.We use the hash method so that each query time is O (1) and the total is O (n).The essence of the hash is to map the value to the address or subscript, if the different key values correspond to the same indice, you need to do chaining processing, bar Indice point

The Group dimension table (Dimension table) is composed. Each dimension table has one dimension as the primary key, and all of these dimension's primary keys are grouped into the primary keys of the fact table. The non-primary key properties of the fact table are called facts (Fact), which are typically numeric or other data that can be computed, while the dimensions are mostly data of type, time, e
