A stack is very useful in situations when data have to be stored and then retrieved in the
—- order.
A) same
B) reverse
C) ascending
D) descending
Step by step
Solved in 3 steps
- C# Reverse the stack - This procedure will reverse the order of items in the stack. This one may NOT break the rules of the stack. HINTS: Make use of more stacks. Arrays passed as parameters are NOT copies. Remember, this is a procedure, not a function. public void ReverseStack(){ }A set of instructions may be used to show a function's return address. Remember that any modifications you make to the stack cannot prevent the procedure from returning to its caller.The return address of a function can be displayed via a series of commands. Keep in mind that any changes you make to the stack must not impede the return of the procedure to its caller
- P3: this is data structure of algorithms subject and topic is all about Stack ApplicationsStacks 1- Write a Python function that takes a user input of a word and returns True if it is a Palindrome and returns False otherwise (Your function should use a Stack data structure). A palindrome is a word that can be read the same backward as forward. Some examples of palindromic words are noon, civic, radar, level, rotor, kayak, reviver, racecar, redder, madam, and refer. 2- Write a Python function that takes a stack of integer numbers and returns the maximum value of the numbers in the stack. The stack should have the same numbers before and after calling the function. 3- Write a main function that tests the functions you wrote in 1 and 2 above and make sure that your code is well documented.* This function evaluates the provided postfix expression. When an operand is encountered, it is added to the stack. When an operator is encountered, two operands are popped, the operation is evaluated, and the result is pushed to the stack.* @param expr string postfix expression representation * @return value of the supplied expression
- C++ ProgrammingActivity: Linked List Stack and BracketsExplain the flow of the main code not necessarily every line, as long as you explain what the important parts of the code do. The code is already correct, just explain the flow SEE ATTACHED PHOTO FOR THE PROBLEM INSTRUCTIONS int main(int argc, char** argv) { SLLStack* stack = new SLLStack(); int test; int length; string str; char top; bool flag = true; cin >> test; switch (test) { case 0: getline(cin, str); length = str.length(); for(int i = 0; i < length; i++){ if(str[i] == '{' || str[i] == '(' || str[i] == '['){ stack->push(str[i]); } else if (str[i] == '}' || str[i] == ')' || str[i] == ']'){ if(!stack->isEmpty()){ top = stack->top(); if(top == '{' && str[i] == '}' || top == '(' && str[i] == ')' ||…Programming Assignment # 3 Objective: To use stacks to solve a programming problem Write a Java program to evaluate infix expression (not necessarily fully parenthesized) using stacks. The priority of operators shall be taken into account. See https://en.wikipedia.org/wiki/Infix_notation for an example of an infix notation. Tip: You would probably need two stacks (a stack for numbers and stack for characters). Input: The program should ask the user to input the infix expression Output: The result of the calculation Assumptions: • You can use the Stack implementation of the Java API, or use one of the ones we have covered in class. • Assume that the input expressions contain only positive integer values, and that the output is always an integer. • The input that the user types can contain any string with the following characters: ( , ) , numbers operators, where numbers is any positive integer and operators are any of +, -, * , / • Your program assumes that the expression is…Expression Conversion Design a program which can tansfer an infix expression into a postfix expression and compute its result. Suppose the infix expression only includes’ *’, ‘/’, ‘+’, ‘-‘, ‘(‘, ‘)’ and the numbers are all integers. [Basic Requirements] 1) You are required to use stack. 2) The infix expression is inputted from keyboard as a string. If the input is legal, please convert the infix expression into postfix expression, calculate the result, and finally output the postfix expression and its value. 3) If the infix expression entered is illegal, the program can prompt the user to input incorrectly and prompt the user to re-enter. Please do the program according to the requirements above and it should be in C language...also after the code i want a report that the algorithm explanations of the code plesse don't just copy other student program and give me back please please please
- C# language Write a program that creates a Queue or Stack (your choice) that represents a list of work orders. This program should use loop, allowing the user to push and pop items on the stack / queue. The program should also allow the user to print all the items in the stack / queue to the console.Python questions: 1) When using a stack to evaluate the balance of brackets and parentheses in an expression, what is the final step? a. at the end of the expression, if a final closing bracket is found, the brackets balance b. at the end of the expression, if the stack is empty, the brackets balance C. at the end of the expression, if the stack is full, the brackets balance d. at the end of the expression, if the stack is empty, the brackets do not balance 2)If the current state of the stack is [x, y, z, t, r] where x is the bottom of the stack and r is the top of the stack, what is the state of the stack and the value returned after two pops operation a. the state is [z, t, r]; x, y are returned b. the state is [x, y]; z, t, r are returned C. the state is [y, z]; x, t, r are returned d. the state is [x, y, z]; t, r are returned 3)What is the resulting postfix expression from the following infix expression? 12 + 5 * 2 - 3 a. 12 5 2^ * +3 - b. 12 5 +2 3^ * - C. 12 5 +2^ *…3- Evaluate the following statement using stack : T= calculate (3) ; Where calculate () defined as follows : int calculate ( int n) { int x , y; if ( n<=1) return 1; else { x = calculate (n – 1) ; y = calculate ( n - 2 ); return x * y; } }
