Trapezium Pattern Printing

Given an integer N as the input, print the pattern as given in the Example Input/Output section.

Input Format:
The first line contains N.

Output Format:
N lines containing the desired pattern.

Boundary Conditions:
2 <= N <= 100

Example Input/Output 1:
Input:
4

Output:
1*2*3*4*17*18*19*20
–5*6*7*14*15*16
—-8*9*12*13
——10*11

Example Input/Output 2:
Input:
7

Output:
1*2*3*4*5*6*7*50*51*52*53*54*55*56
–8*9*10*11*12*13*44*45*46*47*48*49
—-14*15*16*17*18*39*40*41*42*43
——19*20*21*22*35*36*37*38
——–23*24*25*32*33*34
———-26*27*30*31
————28*29
