It’s just funny but I noticed something while solving the prev years problems for ZCO.

Check out these two problems. They are basically the exact same.
In fact i reused the entire code for SUPW into IPL with only 2 lines extra.
And to think they came in the same year. I mean come on. How lucky were they?!!
