The each_cons() of enumerable is an inbuilt method in Ruby iterates for consecutive N elements starting from each element every time. If no block is given, it returns the enumerator.
Syntax: enu.each_cons(N) { |obj| block }
Parameters: The function takes the block which is used to check the condition and N which specifies the number of consecutive elements to take.
Return Value: It returns the elements iterative consecutive for each element.
Example 1:
# Ruby program for each_cons method in Enumerable # Initialize enu = ( 1 .. 5 )
# returns each element enu.each_cons( 2 ){|obj| p obj}
|
Output:
[1, 2] [2, 3] [3, 4] [4, 5]
Example 2:
# Ruby program for each_cons method in Enumerable # Initialize enu = ( 1 .. 10 )
# returns each element enu.each_cons( 4 )
|
Output:
Enumerator: 1..10:each_cons(4)
