The maximum value in this array.
Ruby array max value.
Then you loop over a k size array once for the initial k max once for the collect and a last time for the compact.
Returns a new array.
Then compact must walk the result of collect to strip out the nil s.
In the first form if no arguments are sent the new array will be empty.

The function takes two optional parameters n and block.
The max by of enumerable is an inbuilt method in ruby returns an array of maximum elements which satisfies the condition of the given block.
If max min or sort is used the objects in the collection must also implement a meaningful operator as these methods rely on an ordering between members of the collection.
Let s understand each of them with the help of example.
The max of enumerable is an inbuilt method in ruby returns the maximum elements or an array containing the maximum n elements in the enumerable.
Max 7 1234 9 78 156 1234 this abuses the properties of the splat operator to create an array object containing all the arguments provided or an.

In this article we will learn how to find maximum array element in ruby.
When a size and an optional default are sent an array is created with size copies of default take notice that all elements will reference the same object default.
