Who Will Get the Job?

MangoSoft is one of the top companies in the software industry all over the world. They have a branch at Bangladesh. Although this branch is new but it has proved its strength. The branch is getting new projects from the head office frequently because of its talented team. The interesting thing is every programmer of this company has a strong competitive programming background. This branch hires junior software engineers every week.

Every week they organize a programming contest and anyone can attend. Each contestant gets a unique score after the contest. MangoSoft hires the contestant who secures the 1st Place. They don’t publish the name of the hired contestant. They only publish the score.
