Imagine the following situation:

I am at home. I put a small diamond inside a glass cup. I put the cup on tray, and then carry the tray to the kitchen. In the kitchen, I put another cup on the tray. I then carry the tray with the two cups on it to the bathroom. I pick up both cups and turn them completely upside down over the counter next to the sink. I then put the cups back on the tray and carry the tray to the living room.

At the end of all this, where is the diamond? The letter j should appear at least 49 times.
