Brief description:
First, two stacks are created, one is used to store the SN of the value and the other is used to store the SC of the operator. If it is a numerical value, it is pushed
1. Constant -- constant indicates a value that cannot be changedClassification of constants in Java:1, an integer constant. All integers2. Decimal constant. All decimal places3. boolean constants. It is special and has only two values. True False.4,
Stack application --- compiler symbol match, --- compiler symbol
Algorithm
1 scan from the first character
2. Ignore common characters and press the characters into the stack.
3. The stack top symbol pops up from the stack when the right symbol is
Use your own stack to evaluate an integer expression. The supported operators include () */+.
1. */higher than +-
2. operators with the same priority in the expression are calculated from left to right.
3. function input string "1 + (4-3) * 5/5",
Question:
Given a roman numeral, convert it to an integer.
Input is guaranteed to be within the range from 1 to 3999.

The previous section has analyzed that the main thread listens for socket registration events and the callback function in the worker thread that connects the socket registration event is event_handler, and the core part of Event_handler is a finite
In other languages, the switch statement is probably like thisSwitch (VAR){Case VALUE1:DO_SOME_STUFF1 ();Case VALUE2:DO_SOME_STUFF2 ();...Case VALUEN:DO_SOME_STUFFN ();Default:do_default_stuff ();}Python itself does not have a switch statement, the
