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.

Famous quotes containing the words simple and/or conversion:
“And would you be a poet
Before you’ve been to school?
Ah, well! I hardly thought you
So absolute a fool.
First learn to be spasmodic—
A very simple rule.
For first you write a sentence,
And then you chop it small;
Then mix the bits, and sort them out
Just as they chance to fall:
The order of the phrases makes
No difference at all.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“The conversion of a savage to Christianity is the conversion of Christianity to savagery.”
—George Bernard Shaw (1856–1950)
