Question 2 (1 point) Which of the following is not part of the algorithm to convert infix to postfix using a stack? O If the next token is an open parenthesis, push the open parenthesis to the stack. O If the next token is a close parenthesis, pop each operator off the stack and place on the output until you reach an open paren and toss the open paren. O If the next token is an operand, push the operand to the output If the next token is an operator, always push the operator onto the stack. Save

Explanation / Answer

Which of the following is not part of the algorithm to convert infix to postfix using a stack?

Correct option: If the next token is an operator, always push the operator onto the stack.

Explanation:

When next token is an operator then POP and output tokens from stack until one of lower priority than the next token is encountered or a left parentheses is encountered or the stack is empty; then push that next token.

In an array based implementation of a Stack, which of the following is false?

Correct option: The push function will always succeed in adding an element to the array.

Explanation:

When the array will be full that means when the number of elements present in the array is equal to the array size then if we want to insert an element into the stack then the push function will not succeed as the stack is already full.
