Answer:
public class TicTacToe //Defining TicTacToe class
{
char board[3][3] ; //Creating a 2D array instance variable
TicTacToe() //Constructor to initialize the array with " - "
{
for( int i = 0;i<3;i++) //Loop for the row of array
{
for(int j = 0;j<3;j++) //Loop for the column of array
{
Board[i][j] = '-'; //Assigning "-" in each cell
}
}
}
public char getter() //Defining getter() method to return the array
{
return Board; //returning the array
}
}

Answer:
def typeHistogram(it,n):
d = dict()
for i in it:
n -=1
if n>=0:
if str(type(i).__name__) not in d.keys():
d.setdefault(type(i).__name__,1)
else:
d[str(type(i).__name__)] += 1
else:
break
return list(d.items())
it = iter([1,2,'a','b','c',4,5])
print(typeHistogram(it,7))
Explanation:
- Create a typeHistogram function that has 2 parameters namely "it" and "n" where "it" is an iterator used to represent a sequence of values of different types while "n" is the total number of elements in the sequence.
- Initialize an empty dictionary and loop through the iterator "it".
- Check if n is greater than 0 and current string is not present in the dictionary, then set default type as 1 otherwise increment by 1.
- At the end return the list of items.
- Finally initialize the iterator and display the histogram by calling the typeHistogram.
The steps I would take are 1. Making a strong password with symbols and numbers. 2. I will set up a 2 way authentication ther for if someone would be trying to hack me I would get an alert in order to stop the attempt. 3 I will not use the same password each time.
