Minesweeper : This question is expected to be quite time-consuming. You may consider skipping it if you don’t have enough time.
Write a program that let you play customized minesweeper. The program will first let user enter a number N, and then a map in N * N size will be created. Also, N mines will be randomly spreaded on the map.

Write a program to let user enter a sequence of numbers, then the program will find the longest palindromic substring , and visualize it using ascii characters. .

Consider the following implementation of a class Square:

public class Square
{
privateintsideLength;
privateint area; // Not a good idea

public Square(int length){
sideLength = length;
}
publicintgetArea(){
area = sideLength * sideLength;
return area;
}
}

Why is it not a good idea to introduce an instance variable for the area? Rewrite the class so that area is a local variable.
