You have an array of N integers. You need to make this array good. An array A1,A2,A3...AN considered to be good if A1 > AN. Inorder to make it good you can swap any two numbers in the array. Also yo perform this operation any number of times on any adjacent pairs of integers in the array A. Find the number of ways in which you can make this array good. NOTE - Two ways are considered same if resulting array after making all the swaps have same A1 and AN. Input First argument of input contains an array of size N denoting A1,A2,A3... AN respectively. (1s A1 ≤ 10^4) (1 s NS 10^5) Output Return an integer which is the number of ways in which you can make given array good. Examples Input 14325 Output

![You have an array of N integers. You need to make this array good. An array A1,A2,A3... AN considered to be good if A1 > AN. Inorder to make it good you can swap any two numbers in the array. Also you can
perform this operation any number of times on any adjacent pairs of integers in the array A. Find the number of ways in which you can make this array good.
NOTE - Two ways are considered same if resulting array after making all the swaps have same A1 and AN.
Input
First argument of input contains an array of size N denoting A1, A2, A3
(1 ≤ A1 ≤ 10^4)
(1 ≤ N≤ 10^5)
Output
Return an integer which is the number of ways in which you can make given array good.
Examples
Input
143 25
Output
10
AN respectively.
Explanation
Testcase 1-
Total number of ways are (5,1),(4,1),(3,1),(2,1), (5,2), (4,2), (3,2), (5,3), (4,3), (5,4). First number in above pair is A[1] and second number is A[N].Note that two ways are considered same if A[1] and A[N] are
same in resulting array after swaps.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6cb2d289-27d0-49af-9148-040905891175%2F5460cdc4-d096-4947-aa59-6f1751dc8d75%2Faisvxgp_processed.jpeg&w=3840&q=75)
