Problem: Write a C++ program to take the number n and an array A of n numbers as input from the user. The program should then contain a function which determines whether the array is in strictly increasing order (in which case the function should return 1), or else determine whether the array is in strictly decreasing order (in which case the function should return 2), and return 3 otherwise. The format of the function is int isIncreasingDecreasing (int *A, int n). The program should then print the value returned by the function on a new line. You must implement this via a function, otherwise you will get no credit. For simplicity, assume that all entries in the array are unique.

Input Format - Non-negative integer n and an array A of n elements
Output Format - The value 1,2 or 3 as described above.

1 <= n < 25

Problem: Write a program to accept an integer n and print an n x n square grid filled with alternating concentric L-shaped patterns using the characters 'o' and 'x'.

The pattern always starts with the character 'o'.

The next row and column are filled with 'x', forming an L shape flipped on the vertical axis.

Then again with 'o', alternating until the entire grid is filled.

Examples

Input:
4

Output:
oxox
xxox
ooox
xxxx

Input:
7

Output:
oxoxoxo
xxoxoxo
oooxoxo
xxxxoxo
oooooxo
xxxxxxo
ooooooo


Input Format

An integer n.


Output Format

Print the n x n pattern of concentric L shapes using 'o' and 'x'.


Note

- Do not print any extra messages such as:
  cout << "Enter a number"
  cout << "The computed answer is"
- Use cout only to print the computed final output.
- Do not print unnecessary spaces.
- Do not hard-code the output.
- If any test case passes by simply printing with cout and without logic, marks will not be awarded.

Problem: Write a program to accept an integer n and print an n x n square grid filled with alternating concentric L-shaped patterns using the characters 'o' and 'x'.

The pattern always starts with the character 'o'.

The next row and column are filled with 'x', forming an L shape flipped on the vertical axis.

Then again with 'o', alternating until the entire grid is filled.

Examples

Input:
4

Output:
oxox
xxox
ooox
xxxx

Input:
7

Output:
oxoxoxo
xxoxoxo
oooxoxo
xxxxoxo
oooooxo
xxxxxxo
ooooooo


Input Format

An integer n.


Output Format

Print the n x n pattern of concentric L shapes using 'o' and 'x'.


Note

- Do not print any extra messages such as:
  cout << "Enter a number"
  cout << "The computed answer is"
- Use cout only to print the computed final output.
- Do not print unnecessary spaces.
- Do not hard-code the output.
- If any test case passes by simply printing with cout and without logic, marks will not be awarded.

Student submission:
#include <simplecpp>
main_program{
int n,x,o,i=1,p=1;
cin >> n;
for(i<=n;){
    i%2=0;
        p=x;
        i++;
}
else{
    p=o;}

        repeat(n){
                repeat(n){
                        cout<<p;
                        p++;
                        int t=1;
                }

                        p=n+t;
                        p=x;
                        t++;
                }
}
