# Method's in set's ..
# 1. s.add(): set ke andr ek element add kr skte h ..

# Operation in set's ..
# 1. len(s): return krega set's me kitna element's h ..
print(len(s))

# 2. s.remove(): ye sets me se ek element's ko remove krta h ..
# print(s.remove(8))

# 3. s.clear(): ye sets ko clear krta h ..

# 4. s.pop(): remove an arbitary element from the set and return the element removed ..

# 5. s.union({}): ye koi do sets ko merge krta h ..
