Description if the factor of a and the factor equal to b,b and equals a, and a≠b, then A, B is an intimate number pair. For example, the sum of all true approximations of 220 (i.e. not their own approximations) is: 1+2+4+5+10+11+20+22+44+55+110=284.

1, the string problem formal definition: The assumption that the text is a length of n T[1..N], and the pattern is an array of length M p[1..m], where m2, Method: First preprocessing based on the pattern, and then find all valid offsets

C # has a unified type system, and all types including primitive types (Int,bool,short,long, etc.) inherit from the object class. Java is slightly different, its original type is not inherited from object, each primitive type has corresponding

Problem:Suppose a sorted array is rotated on some pivot unknown to you beforehand.(i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2 ).You is given a target value to search. If found in the array is return its index, otherwise return-1.Assume no

State mode: When an object's internal state changes to allow its behavior to change, the object looks like it has changed its class.The state mode mainly solves the situation when the conditional expression that controls an object state transition

Sometimes we need to determine whether a class implements an interface (Interface), such as when using the reflection mechanism (Reflection) to find a particular type.In simple terms, you can use the Type.isassignablefrom method: 12
