Ruby | Enumerable each_cons() function

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)
