List of top Geographic Information System Questions on Raster Data Analysis and Map Algebra (Conditional Reclassification)

A typical conditional function has the form:
Output = CON (test, out if true, out if false)

What will be the reclassified output if the following conditional reclassification function Output = CON (Layer P < 3, Layer Q, Layer R) is applied on the three input raster layers P, Q, and R?

Layer P

1	3	1
0	5	2
4	2	5

Layer Q

x	x	y
x	x	x
x	x	y

Layer R

b	b	b
a	b	b
a	b	b
