PROGRAMMING:Find all integers that meet the condition
This problem requires the preparation of procedures, the input of $$n $$integers into the array $$a $, and then in the array $$a $$to find the given $$x $. If the value of elements in array $$a $$is the same as that of $$x $$, the subscripts of all elements meeting the conditions are output (subscripts start from 0); If not found, output "not found".
###Input format:
On line 1, enter a positive integer $$n $($$0 < n / Le 10 $$) and an integer $$x $$, and on line 2, enter $$n $$integers separated by spaces. The topic guarantees that the data does not exceed the range of long integers.
###Output format:
If found, output the subscripts of all elements with the same value as $$x $, one subscript per line; If not, output "not found" in one line.
###Input sample 1:
```in
5 9
2 9 8 1 9
```
###Output sample 1:
```out
one
four
```
###Input sample 2:
```in
10 101
2 8 10 1 9 8 -101 0 98762 1
```
###Output sample 2:
```out
Not Found
```
