If ((its precedence value is greater than the precedence value of the character on top) OR (precedence is same AND associativity is right to left)), push.But in case of right to left associativity, we need to treat it as higher precedence and push it to the stack. We need to consider the same if the two operators have left to associativity. In the above implementation, when we see an operator with equal precedence, we treat it same as lower. The postfix of “a^b^c” would be “abc^^”, but the above solution would print postfix as “ab^c^” which is wrong.

How to handle operators with right to left associativity?įor example, power operator ^. The above method handles right associativity of exponentiation operator (here, ^) by assigning it higher precedence value outside stack and lower precedence value inside stack whereas it’s opposite for left associative operators.īelow is the implementation of the above approach: Pop the remaining elements from stack and print them.Repeat steps 1-4 until input expression is completely read.

If stack becomes empty before encountering ‘(‘, then it’s a invalid expression.

If the input character is ‘)’, then pop and print until top is ‘(‘.

If its precedence value is lower or equal then pop from stack and print while precedence of top char is more than the precedence value of the input character.

If its precedence value is greater than the precedence value of the character on top, push.

If stack is empty push it to the stack.

If the input character is an operand, print it.

Recommended: Please try your approach on first, before moving on to the solution.
