Clutch pedal goes to the floor with no resistance

What is your question?

Got into my car the other day pressed down on the clutch and it went down to the floor with no resistance at all and wont come back up unless i pull it up with my hand. Clutch(brake) fluid leak somewhere under the car. Do you think it’s the slave cylinder that needs replaced or the master cylinder? Also can the master cylinder be bad even if the leak isn’t coming from the master cylinder? Thanks
