A Simple Conversion
- Input: 3+4
- Add 3 to the output queue (whenever a number is read it is added to the output)
- Push + (or its ID) onto the operator stack
- Add 4 to the output queue
- After reading the expression pop the operators off the stack and add them to the output.
- In this case there is only one, "+".
- Output 3 4 +
This already shows a couple of rules:
- All numbers are added to the output when they are read.
- At the end of reading the expression, pop all operators off the stack and onto the output.

“Religion is the dream of the human mind. But even in dreams we do not find ourselves in emptiness or in heaven, but on earth, in the realm of reality; we only see real things in the entrancing splendor of imagination and caprice, instead of in the simple daylight of reality and necessity.”
—Ludwig Feuerbach (1804–1872)
“The conversion of a savage to Christianity is the conversion of Christianity to savagery.”
—George Bernard Shaw (1856–1950)
