Implement the following operations of a stack using queues.
Push (x) –push element x onto stack.
Pop () –removes the element on top of the stack.
Top () –get the top element.
Empty () –return whether the stack is empty.
Notes:
You may assume this all operations is valid (for example, no pop or top operations would be called on an empty stack).
Depending on your language, queue May is not supported natively. You could simulate a queue by using a list or dequ

First, the concept
1. Left join the left outer join
To the left table, go to the right table to find the same field, if more than one will be listed in sequence
2. Connect Join
Find the same records around the same
3. Fully connected full outer join
Includes two table join results, left side not found in the right side results (NULL), the right side is not found on the left side of the result

+ A * D * I + C * B * I-B * D = A * C-B * D + (A * D + B * C) * I
Plural division Z1/Z2 = (a + B * I)/(C + D * I)
Z x z * is a real number.
So the plural division Z1/Z2 = (a + B * I) * (c-d * I)/(C2 + D2) =... = (A * C + B * D)/(A2 + b2) + (B * C-A * D) * I)/(A2 + b2)
The last 1/z = 1/(a + B * I) of z1 can also be converted to: A/(A2 + b2) + B * I/(A2 + b2)
Z1 norm | z | = SQRT (A2 + b2) = SQRT (Z × z *)

four, quaternion class static method
There are 9 static methods in Quaternion: Angle method, Dot method, Euler method, Fromtorotation method, inverse method, Lerp method, Lookrotation method, Rotatetowards method and Slerp method. The use of static methods is to call their static methods directly with class names, such as Quaternion.angle (Q1,Q2), and to do analysis under these static methods.
Q is in P1, p2 is inside the rectangle of the diagonal vertex
4. Determine whether two line segments are Intersection
We can determine whether two line segments overlap in two steps:
(1). Rapid Rejection Test
Set the rectangle with the linestring P1P2 as the diagonal line to R and the rectangle with the linestring q1q2 as the diagonal line to T. If the R and t do not intersect, the two linestring obviously do not;
(2). Cross-Site Test
If the two line segments overlap, the two lines must cross e
