This is where people were turned into numbers. The minimum back-up duration recommended is 72 hours, and the Code acknowledges that there could well be circumstances where a longer stand-by period is justified e.

In order to code the algorithm in Python, we will use a dictionary called prec to hold the precedence values for the operators. The answer is that the operators are no longer ambiguous with respect to the operands that they work on. We can now start to see how the conversion algorithm will work. If the scanned character is an Operator and the stack is not empty, compare the lostfix of the character with the element on top of the stack.
The order in which the operators appear is not reversed. Infix to postfix conversion Scan through an expression, getting one token at a time. Conventional notation is called infix notation. If the stack is empty or contains a left parenthesis on top, push the incoming operator onto the stack. The given expression has parentheses to denote the precedence.
Where did go parentheses go? Next token is again a close paranthesis, so we will pop all the operators and add them to the expression string until we reach the open parenthesis and we will pop the open parenthesis as well from the operator stack.
We will show this in a table with three columns. Something very important has happened. Operators of higher precedence are used before operators of lower precedence. The rule for converwion 2 is to push an operator onto the stack if it is empty.
