Program to Reverse an Array.

Reverse an Array

Reversing an array is one of the frequently asked questions by many companies and also in competitive programming. So here, I come with a easy solution for reversing an array in easy way.

Steps:

• Start the loop from size of array -1.
(Let n is size of array so we will start loop i = n-1 i.e loop will be started from last of array.)
• Value of i should be always greater than 0.
• Then decrement i (i--).
• At last print the reversed Arrays.

CODE:

public class Reverse_Array {
public static void main(String[] args) {
int arr[] = {1,2,3,4,5,6,7,8};
int n = arr.length;
reverseArray(arr,n);
}
static void reverseArray(int arr[], int n)
{
System.out.print("Reversed Array is: ");
for(int i=n-1; i>=0; i--) {
System.out.print(arr[i]+" ");
}
}
}
