infix expression variable suffix expression @ (Algorithmic Learning) Converting infix to a corresponding suffix requires that the stack be changed according to the priority.The specific operation is: we can use a stack, storage is the symbol stack,

The logon interface is the entrance to most software. Only users here can use the software normally. Most of our company's systems also have distinctive logon interfaces. A logon interface is relatively simple in terms of functions and interfaces,

A stack is an abstract data structure that "goes first and out". For example: when we wash dishes, wash a plate, put it on the top of a stack of plates, but after we have all washed, if we have a plate, we will start from the top plate, this example

But I also told People later, because there are too many parameters to accept, so if you don't write smart tips very clearly, even I often do not know how to use. However, the acceptance of many parameters, in addition to the easy to mistake usage,
