		for (int i=0;i<arr.length;i++) {
			boolean isDistinct = false;
			for (int j=0;j<i;j++) {
				if(arr[i] == arr[j]) {
					isDistinct = true;
					break;
				}
			}
			if(!isDistinct) {
				System.out.print(arr[i]+" ");
			}
		}
	}
	public static void main(String a[]) {
		int[] nums = {
			5,2,7,2,4,7,8,2,3
		}
		;
		MyDisticntElements.printDistinctElements(nums);
	}
