Problem Statement

Given is a permutation P_1, \ldots, P_N of 1, \ldots, N.
Find the number of integers i (1 \leq i \leq N) that satisfy the following condition:

For any integer j (1 \leq j \leq i), P_i \leq P_j.

Constraints

1 \leq N \leq 2 \times 10^5

P_1, \ldots, P_N is a permutation of 1, \ldots, N.

All values in input are integers.

Input

Input is given from Standard Input in the following format:

N
P_1 ... P_N

Output

Print the number of integers i that satisfy the condition.

Sample Input 1

5
4 2 5 1 3

Sample Output 1

3

i=1, 2, and 4 satisfy the condition, but i=3 does not - for example, P_i > P_j holds for j = 1.

Similarly, i=5 does not satisfy the condition, either. Thus, there are three integers that satisfy the condition.

Sample Input 2

4
4 3 2 1

Sample Output 2

4

All integers i (1 \leq i \leq N) satisfy the condition.

Sample Input 3

6
1 2 3 4 5 6

Sample Output 3

1

Only i=1 satisfies the condition.

Sample Input 4

8
5 7 4 2 6 8 1 3

Sample Output 4

4

Sample Input 5

1
1

Sample Output 5

1

Solution in Python (3.4.3) (judge verdict: Accepted)

n = int(input())
p = list(map(int,input().split()))
#n = 8
#p = [5,7,4,2,6,8,1,3]


m = [0] * n
m[0] = p[0]

for i in range(1,n):
  m[i] = min(m[i-1],p[i])

#p , m ([5, 7, 4, 2, 6, 8, 1, 3], [5, 5, 4, 2, 2, 2, 1, 1])

ans = 0
for i in range(n):
  if m[i] >= p[i]:
    ans += 1

print(ans)
