- 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 codeQ4. Write a program that read 2 matrices and has a function which finds their sum. Q5. Write a program that read 2 matrices and has a function which finds their multiplication. Q6. Write a program that handles a list of numbers where it has the following functions - Function that finds their average and sum - Function that finds their maximum and minimum - Function that search for a given number in that list. - Function that count the occurrence of a given number in that list. Then the program should do the following: - Read the list - Find the average and the sum of that list - Find the minimum and the maximum of that list - Count the occurrence of a given number in that list.the Program in C++, Write a program that evaluates a valid postfix expression such as: 6 2 + 5 * 8 4 / -The program should read a postfix expression consisting of digits and operators into a string. Using modified versions of the stack functions implemented earlier in this chapter, the program should scan the expression and evaluate it. The algorithm is as follows: 1-While you have not reached the end of the string, read the expression from left to right. If the current character is a digit, Push its integer value onto the stack (the integer value of a digit character is its value in the computer’s character set minus the value of '0' in the computer’s character set). Otherwise, if the current character is an operator, Pop the two top elements of the stack into variables x and y. Calculate y operator x. Push the result of the calculation onto the stack. 2-When you reach the end of the string, pop the top value of the stack. This is the result of the postfix expression. [Note: In Step…

- PLEASE DO NOT USE BUILT IN FILES OR FUNCTIONS! Write a program in c++ and make sure it works, that reads a list of students (first names only) from a file. It is possible for the names tobe in unsorted order in the file but they have to be placed in sorted order within the linked list.The program should use a doubly linked list.Each node in the doubly linked list should have the student’s name, a pointer to the next student, and apointer to the previous student. Here is a sample visual. The head points to the beginning of the list. Thetail points to the end of the list.When inserting consider all the following conditions:if(!head){ //no other nodes}else if (strcmp(data, head->name)<0){ //smaller than head}else if (strcmp(data, tail->name)>0){ //larger than tail}else{ //somewhere in the middle} When deleting a student consider all the following conditions:student may be at the head, the tail or in the middleBelow, you will find a sample of what the…: Write a recursive function to multiply two positive integers without usingthe * operator (or / operator). You can use addition, subtraction, and bit shifting, but you shouldminimize the number of those operations.Problem Statement: Consider an input string PAL of letters ‘P’, ‘A’, and ‘L’. This string, which is given by the user, ends with ‘#’. It should be stored in a table (or array), called PAL_TAB. The number of each of these letters is unknown. We have a function, called SWAP(PAL, i, j), which places the ith letter in the jth entry of string PAL and the jth letter in the ith entry of PAL. Note that SWAP(PAL, i, j) is defined for all integers i and j between 0 and length(PAL) – 1, where length(PAL) is the number of letters of PAL. 1. Using our algorithmic language, write an algorithm, called Sort_PAL, which sorts the letters in the array PAL_TAB in a way that all P’s appear first, followed by all A’s, and followed by all L’s. The algorithm Sort_PAL should have one parameter: The array PAL_TAB. Also, your solution is correct only if the four constraints below are satisfied: - Constraint 1: Each letter (‘A’, ‘L’, or ‘P’) is evaluated only once. - Constraint 2: The function SWAP(PAL, i, j) is…
