The mere fact that you remained in the country for a one year period should not alone result in the denial of your entry. However, it could cause the government to question you more carefully than they might otherwise about the purpose of your US visit, and they may also question you about your prior stays. If they suspect that you engaged or will engage in activities not permissible on a tourist visa, such as working, they could deny you admission. It is a good idea to bring with you proof of your ties to your home country (such as a job letter, school enrollment letter, proof of property ownership, etc) and proof of sufficient financial means to cover your stay in the US (such as a bank statement) to address, if necessary, any concerns the government may have about whether you intend to immigrate or engage in unauthorized activities in the US. This all having been said, most problems tend to arise when foreigners try returning to the US after a short absence, which does not seem to be the case here.
