1: Problem Statement:
In Second year Computer Engineering class of M students, set A of students play cricket and set B of students play badminton. Write C/C++ program to find and display-
i. Set of students who play either cricket or badminton or both
ii. Set of students who play both cricket and badminton
iii. Set of students who play only cricket
iv. Set of students who play only badminton
v. Number of students who play neither cricket nor badminton 
(Note- While realizing the set duplicate entries are to avoided)

9: Program Setatement A palindrome is a string of character that‘s the same forward and backward. Typically, punctuation, capitalization, and spaces are ignored. For example, ‖Poor Dan is in a droop‖ is a palindrome, as can be seen by examining the characters ―poor danisina droop‖ and observing that they are the same forward and backward. One way to check for a palindrome is to reverse the characters in the string and then compare with them the original-in a palindrome, the sequence will be identical. Write C++ program with functions- 1. to check whether given string is palindrome or not that uses a stack to determine whether a string is a palindrome. 2. to remove spaces and punctuation in string, convert all the Characters to lowercase, and then call above Palindrome checking function to check for a palindrome 3. to print string in reverse order using stack Program: #include<iostream> #include<string.h> #define MAX 100 using namespace std;  struct stack ...
