Assume we have already defined a variable of type int called num with the following line of code:

int num = ???; // 'num' can have any int value

TASK: Print a Triforce composed of 3 centered triangles created with num asterisks (*) on the bottom row, num - 2 asterisks on the next bottom row, ..., and 1 asterisk on the top row, and such that the triangles are surrounded by hyphens (-). You can assume that num is odd and is at least 3.

EXAMPLE: If num is 5, the resulting Triforce would be the following:

-----*----- ----***---- ---*****--- --*-----*-- -***---***- *****-*****

Sample Input:

5

Sample Output:

-----*----- ----***---- ---*****--- --*-----*-- -***---***- *****-*****
