I just started this journey now. I'm just feeling that I'm really stupid. Others are performing really well on contests. I'm not many times able to pick up the AD-hoc idea for Div-2 B and many times not able to implement it clearly. I often implement it in really complex way which leads to wrong answers on edge cases and other silly small mistakes. And can I aim to become master? Haha I'm daydreaming too much.
