Repeat this step as long as stack is not empty.

(After all characters are scanned, we have to add any character that the stack may have to the Postfix string.) If stack is not empty add topStack to Postfix string and Pop the stack.

Repeat this step till all the characters are scanned. Repeat this step as long as stack is not empty and topStack has precedence over the character. If topStack has higher precedence over the scanned character Pop the stack else Push the scanned character to stack.

If the scanned character is an Operand and the stack is not empty, compare the precedence of the character with the element on top of the stack ( topStack).

If the scanned character is an operator and if the stack is empty Push the character to stack.
