Here is an infix expression: 4 + 3*(6*3-12). Suppose that we are using the usual stack algorithm to convert the expression from infix to postfix notation. The maximum number of symbols that will appear on the stack AT ONE TIME during the conversion of this expression?

Correct Answer: 4
When we perform the conversion from infix to postfix expression +, *, (, * symbols are placed inside the stack. A maximum of 4 symbols are identified during the entire conversion.

Given two processes (conversion of postfix equation to infix notation and conversion of prefix notation to infix notation), which of the following is easier to implement?

To convert the postfix expression into the infix expression we use stack and scan the postfix expression from left to right.

Convert the following Infix expression to Postfix form using a stack. x + y * z + (p * q + r) * s, Follow usual precedence rule and assume that the expression is legal.

Consider the usual algorithm for determining whether a sequence of parentheses is balanced. Suppose that you run the algorithm on a sequence that contains 2 left parentheses and 3 right parentheses (in some order). The maximum number of parentheses that appear on the stack AT ANY ONE TIME during the computation?

Which data structure is needed to convert infix notation to postfix notation?

Consider the usual algorithm for determining whether a sequence of parentheses is balanced. The maximum number of parentheses that appear on the stack AT ANY ONE TIME when the algorithm analyzes: (()(())(()))?

You are asked to perform a queue operation using a stack. Assume the size of the stack is some value ‘n’ and there are ‘m’ number of variables in this stack. The time complexity of performing deQueue operation is (Using only stack operations like push and pop)(Tightly bound).

What is the time complexity of an infix to postfix conversion algorithm?

Mr A started half an hour later than usual for the marketplace. But by increasing his speed to $$\frac{3}{2}$$ times his usual speed he reached 10 minutes earlier than usual. What is his usual time for this journey?

In the following passage, some of the words have been left out. Read the passage carefully and select the correct answer for the given blank out of thefour alternatives.
That is why publicly invoking these symbols has to be an act of responsible citizenship and not self­____________ demagoguery, but thedifference can be hard to _______________. The problem with emotive symbols is that _________________ they can multiply the force ofarguments, they cannot replace the arguments__________________. All persuasion harnesses symbols but principled persuasion must alsoprovide arguments that can be _____________ debated. The problem with emotive symbols is that _________________ they can multiply the force of arguments,
