Reversing Arrays, Array.Reverse()


Reversing Arrays, Array.Reverse()

will help you arrInput.Reverse uses LINQ Reverse method which doesn't change the original collection. You need to call ToArray on it
code :
var reversed = arrInput.Reverse().ToArray();

Sorting an array in reverse order - not reversing

will help you The most "easy" solution would be to use the reverseComperator provided by the Collections class. This will automaticly sort the array in a descending order.
code :
public static void main(String[] args) {
    // Use the Wrapper class, otherwise you can´t call Arrays.sort with a comperator.
    Integer[] array = {2, 6, 4, 1};
    Arrays.sort(array, Collections.reverseOrder());
    for (int num : array) {
        System.out.println(num);
    }
}

Hope this helps Array#reverse works in place and doesn't create a new array. The line
code :
var reversed = a.reverse(); 
var a = ['one', 'two', 'three'];
var reversed = a.reverse(); 

reversed.push(1000); // add something to reversed

console.log(a);        // ['three', 'two', 'one', 1000]
console.log(reversed); // ['three', 'two', 'one', 1000]
var a = ['one', 'two', 'three'];
var reversed = a.slice().reverse(); 

console.log(a);        // ['one', 'two', 'three']
console.log(reversed); // ['three', 'two', 'one']

seems to work fine Arrays are objects, so: reference-types.
It is passing a reference - by value. So: if you change what the reference points to (i.e. the array data), that change will still be visible to everyone who also has a reference to that same object.
