5

Sample Output:

1
3*2
4*5*6
10*9*8*7
11*12*13*14*15

Sample Input:
6
Sample Output:
1
3*2
4*5*6
10*9*8*7
11*12*13*14*15
21*20*19*18*17*16

solution:

#include <iostream> 
using namespace std; 
void printPattern(int n) 
{ 
	int j, k = 0; 
	for (int i=1; i<=n; i++) 
	{ 
	
		if (i%2 != 0) 
		{ 

			for (j=k+1; j<k+i; j++) 
				cout << j << "*"; 
			cout << j++ << endl; 

			k = j;	 
		} 

		else
		{ 

			k = k+i-1; 
			for (j=k; j>k-i+1; j--) 
				cout << j << "*"; 
			cout << j << endl;	 
		} 
	} 
} 

int main() 
{ 
	int n;
 	cin>>n;
	printPattern(n); 
	return 0; 
}
