- 10 - final question If you create a new empty stack and push the values 1, 2, and 3 in that order, and call pop on the stack once, Which value will be returned? а. 1 b. 2 С. 3Q1: Write a java application for the stack operations with Linked List. Q2: Write java program to take the order from the customer and display the ordered items and total payment. If customer is entering the wrong name or not following the order to enter the menu it has to display error messages. (Find in the sample code) Sample Output:4. Evaluate the following postfix expression. 3 55 * + 5 7 + 6/- The value of the above postfix expression is a 26 b. 22 Write step by step procedure of solving this problem. Your Answer is (a or b) Use the above stack and fill (push) in numbers. Type "pop" beside the number when you need to pop it out. Finally, find the postfix expression value. Next
- 15 - final question When you call pop on a stack, the element is removed from the stack relative to the other elements. а. Тор b. BottomTry a spatuladef pancake_scramble(text):Analogous to flipping a stack of pancakes by sticking a spatula inside the stack and flipping over the stack of pancakes resting on top of that spatula, a pancake flip of order k performed for the text string reverses the prefix of first k characters and keeps the rest of the string as it were. For example, the pancake flip of order 2 performed on the string 'ilkka' would produce the string 'likka'. The pancake flip of order 3 performed on the same string would produce 'klika'.A pancake scramble, as defined in the excellent Wolfram Challenges programming problems site, consists of the sequence of pancake flips of order 2, 3, ... , n performed in this exact sequence for the given n-character text string. For example, the pancake scramble done to the string 'ilkka' would step through the intermediate results 'likka', 'kilka', 'klika' and 'akilk'. This function should compute and return the pancake scramble of its parameter text string. text…checkBalance Language/Type: Java Stack collections string Related Links: String Write a method named checkBalance that accepts a string of source code and uses a Stack to check whether the braces/parentheses are balanced. Every ( or { must be closed by a } or ) in the opposite order. Return the index at which an imbalance occurs, or -1 if the string is balanced. If any ( or { are never closed, return the string's length. Here are some example calls: // index 0123456789012345678901234567890 checkBalance("if (a(4) > 9) { foo(a(2)); }") returns -1 because balanced checkBalance("for (i=0;i<a(3};i++) { foo{); )") // returns 14 because } out of order checkBalance("while (true) foo(); }{ ()") returns 20 because } doesn't match any { checkBalance("if (x) {") returns 8 because { is never closed // // // Constraints: Use a single stack as auxiliary storage.
- First picture: create a complete programming codes about the picture. Use pre-defined for stack. Sencond Picture: Test results or the supposed outcome of the programming. Note: put a comment in every line to describe what is the function of each specific codes, variables, etc.In creating local variables on the stack (e.g. in the same way we store saved values there), you simply the number of bytes required by each variable from the stack pointer. O subtract O addQ2: Write a program that reverses the string "your name" using Stack parameters. You can hardcode your name or you can take it from the user.
- 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(){ }Represents an integer evaluator of postfix expressions. Assumes the operands are constants. Evaluates the specified postfix expression. If an operand is encountered, it is pushed onto the stack. If an operator is encountered, two operands are popped, the operation is evaluated, and the result is pushed onto the stack. param expr string representation of a postfix expression return value of the given expression use java to codeTask:implement a function that reverses a list of elements by pushing them onto a stack in one order and writing them back to the list in reversed order P.S:Answer must be in python
