lintcode python and C++打印X图形

一开始实现了怎么把那个x图形用C++打印出来，但是想不明白怎么用他说的那样输出

 C++实现输出

#include 
using namespace std;
int main()
{
	char x[100];
	int n;
	cout << "请输入:" << endl;
	cin >> n;
	int i=0;
	int j=0;
	for (i = 1; i <= n; i++) {
		for (j = 1; j <= n; j++) {
			if (i==j||i + j == n+1) {
				cout << "*";
			}
			else
			{
				cout << " ";
			}

		}
		cout << endl;
	}
	return 0;
}

python 打印x图形

x = int(input("输入:"))
for i in range(1,x+1):
    for j in range(1,x+1):
        if( i==j or i+j==x+1):
            print("x",end=' ')
            # s+='x'
        else:
            print(" ",end=' ')
            # s+=' '
    print('n')

python 达到符合的要求 

def cut(obj, sec)://字符串按固定长度分割
    return [obj[i:i+sec] for i in range(0,len(obj),sec)]
s=''
x = int(input("输入:"))
for i in range(1,x+1):
    for j in range(1,x+1):
        if( i==j or i+j==x+1):
            # print("x",end='')
            s+='x'
        else:
            # print(" ",end='')
            s+=' '
s2=cut(s,x)
print(s2)
