When I solve a problem, I get a quick analysis telling me my solution was faster than x% of submissions, and used less memory than y% of solutions. I tend to get really good figures for x and bad ones for y, which is better than vice versa (can't get back time), but sometimes y is a single-digit number, and I know I'm compared against only submissions using the same language... so someone out there has a way more efficient solution than mine, and I'd like to see it!

Generally speaking the solutions in the Solution pane are Java or Python, and I'm using C# most of the time, so I basically never get to see an optimized solution. I learn very well by taking apart successful solutions and absorbing what worked about them - so I'd really like to see which solutions were better than mine in terms of speed and space.
