    Sorry for my unoptimize code

    def print_rangoli(size):
    alpha = "abcdefghijklmnopqrstuvwxyz"
    last_word = ""
    total_char = ((size - 1) * 4) + 1
    
    for i in range(size - 1, -1, -1):
        temp = alpha[i]
        
        for j in range(len(last_word) - 1, -1, -1):
            temp = last_word[j]+"-"+temp+"-"+last_word[j]
        
        print(temp.center(total_char, "-"))
        last_word += alpha[i]
    
    for i in range(1, size):
        temp = alpha[i]
        
        for j in range(i + 1, size):
            temp = alpha[j]+"-"+temp+"-"+alpha[j]
        
        print(temp.center(total_char, "-"))

    after 4 goddamen hours: howtf this is easy !

    def print_rangoli(size): # make a map for the alphapets dicta={0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e', 5: 'f', 6: 'g', 7: 'h', 8: 'i', 9: 'j', 10: 'k', 11: 'l', 12: 'm', 13: 'n', 14: 'o', 15: 'p', 16: 'q', 17: 'r', 18: 's', 19: 't', 20: 'u', 21: 'v', 22: 'w', 23: 'x', 24: 'y', 25: 'z'}

    width = (4 * size) - 3

def line_op(size, rang):
    L=[dicta[size-i-1] for i in range(rang)]
    R=list(reversed(L))
    R.pop(0)
    line=L+R
    return("-".join(line))
half=[]
for i in range(size):
    q1=line_op(size, i+1)
    while len(q1) < width:
        q1="-"+q1+"-"
    half.append(q1)

half.extend(reversed(half[0:-1]))
for i in half: print(i)

    if name == 'main': n = int(input()) print_rangoli(n)****
