1)An image generator is designed. There are 4 numbers (keys for 4 rectangular objects surrounding box key). For example 3 is a tree shape rectangle (dimensions are ax3a). Each box may correspond to 4 objects. 3 may be tree, house, hill etc... A picture totally consists of B objects. So random B numbers and 4 totally Bx4 numbers are generated and put on the papers. The details of inside B shapes are P lines are dr9awn afterwards.

a)Write an algorithm

b)What is the complexity
