q ß q - 1
S[q] ß V[m]
Else if V[m] is an operator then push it into the operator stack. 6. Ignore Right parenthesis. 7. If the V[m] is a Left parenthesis than
pop operator1 from the operator stack :
operator1 ß operator at top of operator stack
q ß q - 1
S[q] ß operater1
End if
- The postfix notation is found in the vector S and is of length (n+1)/2

Program to convert a infix expression in to postfix and prefix expression in php?
To convert an infix expression to postfix and prefix in PHP, you can implement the Shunting Yard algorithm for postfix conversion and a modified approach for prefix conversion. For postfix, you use a stack to reorder operators based on their precedence and associativity while scanning the infix expression. For prefix, you can reverse the infix expression, convert it to postfix, and then reverse the resulting postfix expression. Here’s a brief code outline for both conversions: function infixToPostfix($infix) { // Implement the Shunting Yard algorithm to convert infix to postfix } function infixToPrefix($infix) { // Reverse the infix expression // Convert to postfix using infixToPostfix // Reverse the postfix result to get prefix } You would need to handle operators, parentheses, and precedence rules within these functions.
