5. fast please Convert the following infix expression into its prefix and postfix equivalents: a / b - (c + d * e) / f * g For any postfix, show the final transformed expression using the stack method for transformation as explained in class showing all the relevant steps. For the prefix, show any needed reversion and the final transformed expression using the stack method for transformation as explained in class showing all the relevant steps. Draw and sequence your diagrams clearly
4. Sort elements in an array-based stack in ascending order, i.e. make the smallest element to be the top element of the stack. E.g. given the stack elements (from bottom to top): 90, 70, 80, 10, sort the elements to make the stack elements become (from bottom to top): 90, 80, 70, 10. The only data structure you can use is array-based stack. In addition to the given stack, you can use only one extra stack to store some temporary data. Given a stack st, use one extra stack, tmpst, to store temporary data. Here are some hints of the idea. Pop out the top element of st to a variable tmp. If the stack tmpst is empty, push tmp onto tmpst; if tmpst is not empty, pop out its top element and push that element onto st until the top element of tmpst is smaller than tmp, then push tmp onto tmpst .. a. Write a program to implement the stack based sorting. b. Take the input (90, 70, 80, 10) as an example. c. Print all the push and pop operations in proper format. d. At the end, print the sorted…
5. Evaluate the following postfix expression. (a + b) * c - (d - e) / f The postfix will be a. abcde f + * - -/ b. a b +c *de-f/- Write step by step procedure of solving this problem. Your Answer is (a or b) Use the above stack and fill (push) in operators, +, -, *, /, and 'C'. Type "pop" beside the operators or '(' when you need to pop it out. Finally, convert the expression from infix to the postfix. Submit Type here to search

Question 3 Not complete Marked out of 1.00 Flag question Evaluate the postfix expression 2 3 5 -* using a stack structure. The algorithm is as follows: • Read the next token from left to right • If the token is an operand, push it onto the stack • If the token is an operator, pop the top two operands from the stack, perform the operation, and push the result back onto the stack • Repeat until there are no more tokens to read Note: • Show the contents of the stack AFTER each "push" operation. • Insert a comma between numbers in the answer box below: Answer: (penalty regime: 0 %) step 1: [ step 2: step 3: [ step 4: [ step 5: Check
