Detailed explanation-1: -Explanation: Using the infix to postfix expression conversion algorithm, the corresponding postfix expression is found to be abc*+de*+.
Detailed explanation-2: -The postfix expression abc+de/*-is equivalent to which of the following infix expression? Hence, correct choice is a-(b+c)*(d/e). So, the equivalent infix expression is (1 + 2) * 3 – (4 * 5) and it’s value is-11.
