Ruby Array Sort

The ruby sort method works by comparing elements of a collection using their operator more about that in a second using the quicksort algorithm.

Ruby array sort.

It s also possible to sort in place using the sort. Let us see an example. This means that the original array will change instead of creating a new one which can be good for performance. A negative index is assumed relative to the end of the array that is an index of 1 indicates the last element of the array 2 is the next to last element in the array and so on.

You can also convert an array to a string transform one array of data into another and roll up an array into a single value. 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. The second form creates a copy of the array passed as a parameter the array is generated by calling to ary on the parameter. Once you have data in an array you can sort it remove duplicates reverse its order extract sections of the array or search through arrays for specific data.

Returns a new array. In the first form if no arguments are sent the new array will be empty. Arrays let you represent lists of data in your programs. Ruby sort arrays use the sort method.

An array of sorted elements. You can also pass it an optional block if you want to do some custom sorting. Ruby arrays can hold objects such as string integer fixnum hash symbol even other array objects. Notice that sort will return a new array with the results.
