The first time a class forms a line, usually the teacher will let the students form a line according to their height, then report the number 1 and 2, and call the students who reach 1 to step forward. In this way, the team will become two lines. Suppose there are n students in a class now, and they have been arranged in a column according to their height. The students are numbered from 1 to n according to their height. Can you tell me which number students are in the first column?
