There have been moments when I just submit my solutions during the last minutes of the contest. But today was one of the best adrenaline rushes I have had while giving a contest. I didn't really like today's problem D because it was just "guessy", so I was struggling to find some pattern that worked. I thought of a solution in the last minutes and with my heart rushing went to coding it. My hands were trembling and I was struggling to implement the solution as my thoughts were all jumbled up. At around 1 minute, I took a look at the timer and the pressure was exhilarating. With just 15-20 seconds left, I finished the implementation and tested the samples. At around 11 secs, I opened the browser and clicked on the 'Submit Code' button. And at almost 1 sec, I submitted my solution. This was a great feeling, but I still hate the problem. :)
