list type, list in Clojure is called Persistentlist, which is a "persistent list", which is a type of immutable data. Clojure's persistent data structure facilitates the creation of "modify" operations (data immutable, "modification", which is essentially new data created) based on existing structures and can be shared as much as possible (structure sharing). The structure sharing of a persistent list can be explained in the following example (from a wiki): (Def

from a program implementation point of view, meet all the simplest logic is that there is a non-satisfied demand to return to the not (circular judgment), and finally the default is true, similar to the rapid failure of the policy, so the result of the empty collection is true. The pseudo code is as follows for x in xs if x is not odd return falsereturn trueIf you use recursive writing to determine whether an array is a singular method Head (

as a non-null value, the simplest logic for meeting all requirements is to return non-(loop judgment) If there is one that does not meet the requirements. In the end, the default situation is true, similar to a fast failure policy, so the result of a null set is true. The pseudocode is as follows: for x in xs if x is not odd return falsereturn trueIf you use recursive writing to determine whether an array is odd or not Head (x) x removes the
