What is the take-last method in Clojure Sequence?
The take sequence method will return a sequence containing the number of selected elements. This selection is made from left to right of the initial sequence.
Use case
This method can be used to select elements from left to right.
Syntax
(take number seqq)
take sequence syntax
Parameters
This method takes the following parameters:
seqq: This represents thesequencecontaining element.number: This is the number of elements we wish to select from the sequence starting from the first element.
Return value
This method returns a sequence containing the selected elements.
Example
(ns clojure.examples.example(:gen-class))(defn func [](def seq1 (seq [1 2 8 9 1 0 6 8 2]))(println (take 3 seq1)))(func)
Explanation
- Line 3: We define a function
func. - Line 4: We define our sequence
seq1. - Line 5: We use the
takemethod to select3first elements from the sequence. Elements1,2, and8will be selected as we would see in the output. - Line 6: We call the
funcfunction. Observe that the output returned all the elements of the sequence selected starting from the first element6,8, and2.
