This works exactly like the each method for an array object with one crucial difference.
Ruby each with index reverse.
Each element in this array is created by passing the element s index to the given block and storing the return value.
In the last form an array of the given size is created.
In the previous challenge we learned about each method being central to all of the methods provided by enumerable class.
For a hash you create two elements one for the hash key and one for the value.
However ruby makes it a cinch.
Here we are going to learn about the array each index method with examples in ruby programming language.
In the last form an array of the given size is created.
Each element in this array is created by passing the element s index to the given block and storing the return value.
New 3 index index 2 0 1 4 common gotchas when sending the second parameter the same object will be used as the value for all the array.
New 3 index index 2 0 1 4 common gotchas when sending the second parameter the same object will be used as the value for all the array.
You can use the array reverse method to reverse the order of the elements in the array before iterating over them.
Ruby more than 5 years have passed since last update.
Here str is the string which is to be reversed.
Reverse is a string class method in ruby which is used to return a new string with the characters from the given string in reverse order.
One of such useful methods is each with index which allows you to iterate over items along with an index keeping count of the item.
This method returns a new string in reversed order.

In this article we will learn about array each index method we have already discussed the array each method you must be little more excited to read about array each index.
