Need advice

Hi i am a begginer in cp . Today i participated in Atcoder begginers contest. I was solving my first question and these guys had already solved 5 problems within 8 mins. It was so demotivating and now i am feeling insecured xD if i can match up the level or not. Need your oppinion on this and please leave some beginner advices for me , btw i use Java for cp. Thanks ~ Ismail

change to c++ , cause its faster, after that i donno man , cause I feel like i am in the same boat here :,)

well converting to c++ might take time not sure. I want to deal the insecurity i have xD plus need advices how to take things along since ive just started cp.

the only way is guess practice , other than that there is no other way :,) unfortunately
