        w = 4*n-3
    chars = []
    line = ""
    lines = []

    for i in range(n):
        chars.append(chr(96+(n-i)))
        line = "-".join(chars + chars[-2::-1])
        lines.append(line.center(w,"-"))

    print("\n".join(lines + lines[-2::-1]))

    chars[-2::-1] is the same as list(reversed(chars[:-1]))

    Used string cropping for this one

    def print_rangoli(size):
    letters = [x for x in range(1, size + 1)]
    string = [chr(ord('a') + n - 1) for n in letters]

    if (size == 1):
        print("".join(string))
        return

    string_reversed = "-".join(string)
    string = reversed(string)
    string = "-".join(string)
    
    size *= 2
    
    for x in range(1, size, 2):
        print(f"{string[:x]:->{size - 1}}-{string_reversed[(size - x + 1):]:-<{size - 3}}")
        
    
    for x in reversed(range(1, size - 1, 2)):
        print(f"{string[:x]:->{size - 1}}-{string_reversed[(size - x + 1):]:-<{size - 3}}")
