Arrange the given steps in CORRECT order of constructing a perpendicular using ruler and compases.
Steps of construction:
1. With A and B as centres and a radius greater than AP construct two arcs, which cut each other at Q.
2. Join PQ. Then 
is perpendicular to l. We write 
3. With P as centre and a convenient radius, construct an arc intersecting the line l at two points A and B.
4. Given a point P on a line l.
A 4-3-1-2
