We need to use terminal operators in order to execute a flow and to receive the values that the flow emits.

These terminal operators are covered:
collect {} - receive all emissions of the flow
first() - returns only the first emission of the flow
last() - returns only the last emission of the flow
single() - returns single emission of a flow, but only if the flow only emits a single value, Otherwise - if the flow emits no values or multiple values - an Illegal state Exception is thrown
toList(), toSet() - operators wait until the flow completes and then all the emissions will be returned as a list or set
fold(), reduce() - to perform operations like summing up all of the emitted values of a flow
