INVARIJANTE
U nekim se zadatcima susrećemo sa sustavom koji se mijenja po određenim pravilima. U takvim je
zadatcima često korisno potražiti neku veličinu koju ta pravila ne mijenjaju. Takvu veličinu, koja se ne mijenja
nikakvom dozvoljenom promjenom sustava, zovemo invarijanta.

Two Basic Counting Principles
In our everyday lives, we often need to enumerate "events" such as, the arrangement of objects in a certain way, the partition of things under a certain condition, the distribution of items according to a certain specification, and so on. For instance, we may come across counting problems of the following types:
"How many ways are there to arrange 5 boys and 3 girls in a row so that no two girls are adjacent?"
"How many ways are there to divide a group of 10 people into three groups consisting of 4, 3 and 2 people respectively with 1 person rejected?"
