For this Question: Given an array Arr of N distinct integers. Find the number of ways to divide the array into some subarrays such that:
> All elements must be in exactly one subarray
> All the subarrays have strictly increasing values
> For any subarray S1 that ends before subarray S2, length of S1 >= length of S2
> For any subarray S1 that ends before subarray S2, S1 should be lexographically smaller than S2

As the number of ways can be huge print answer modulo 1000000007.First line of input contains a single integer N.
Second line contains N integers, denoting array Arr.

Constraints:
1 <= N <= 1000
1 <= Arr[i] <= 1000Print the answer modulo 1000000007.Sample Input
4
1 3 2 4

Sample Output
2

Explanation:

Division 1: (1, 3) (2) (4)
Lengths of subarrays: 2 1 1 (non increasing)
Subarray (1, 3) is lexographically smaller than (2) which is lexographically is smaller (4)

Division 2: (1, 3) (2, 4)
Lengths of subarrays: 2 2 (non increasing)
Subarray (1, 3) is lexographically smaller than (2, 4)., I have written this Solution Code: #pragma GCC optimize ("Ofast")
