GCSE AQA Computer Science Designing, Creating & Refining Algorithms: The following subroutines contro

Question

The following subroutines control the way that labelled blocks are placed in different columns.

BLOCK_ON_TOP(column) returns the label of the block on top of the column given as a parameter.
MOVE(source, destination) moves the block on top of the source column to the top of the destination column.
HEIGHT(column) returns the number of blocks in the specified column.

This is how the blocks A, B and C are arranged at the start.

Column 0        Column 1        Column 2
C               -               -
B               -               -
A               -               -

Draw the final arrangement of the blocks after the following algorithm has run.

MOVE(0, 1)
MOVE(0, 2)
MOVE(0, 2)
