thank you for your comment, yes code formatting, guidelines are good. I havent talked to team lead yet. I talked to the Sr engineer several times, and often times he comes up with different approach to the problem and ask me to implement his solution even if my version has passed all test cases) it makes me sad

If there has been no explanation for a requested change, ask for one. A reviewer should never ask for changes for change's sake, they need to have a reason. So ask for that reason, then you can decide whether to push back or not, or ask for further clarification.
