#TODO 2:
# CSS colors are defined using a hexadecimal (HEX) notation for the combination of Red, Green, and Blue color values (RGB).
# Specifications of HEX Color Code
#
# ■ It must start with a '#' symbol.
# ■ It can have  3 or 6  digits.
# ■ Each digit is in the range of 0  to F. (1,...,9,0,A,B,C,D,E and F).
# ■  A-F letters can be lower case. (a,b,c,d,e and f are also valid digits).
# Valid Hex Color Codes
# #FFF
# #025
# #F0A1FB
# Invalid Hex Color Codes
# #fffabg
# #abcf
# #12365erff
# You are given N lines of CSS code. Your task is to print all valid Hex Color Codes, in order of their occurrence from top to bottom.
# CSS Code Pattern
# Selector
# {
# 	Property: Value;
# }
# Input Format
# The first line contains N, the number of code lines.
# The next N lines contains CSS Codes.
# Constraints  0 < N < 50
# Output Format: Output the color codes with '#' symbols on separate lines.
# Sample Input
# 11
# #BED
# {
#     color: #FfFdF8; background-color:#aef;
#     font-size: 123px;
#     background: -webkit-linear-gradient(top, #f9f9f9, #fff);
# }
# #Cab
# {
#     background-color: #ABC;
#     border: 2px dashed #fff;
# }
# Sample Output
# #FfFdF8
# #aef
# #f9f9f9
# #fff
# #ABC
# #fff

# ss_list=[
#     '#BED',
#     '{',
