### Instructions
Write a program named `hiddenp` that takes two `string` and that, if the first `string` is hidden in the second one, displays `1` followed by a newline (`'\n'`), otherwise it displays `0` followed by a newline.
Write a program named `hiddenp` that takes two `strings` as arguments. The program should check if the first string `s1` is hidden in the second `s2`.
`s1` is considered hidden in `s2` if it is possible to find each character from `s1` in `s2`, in the same order as they appear in `s1`, but not necessarily consecutively.
Let s1 and s2 be `string`. It is considered that s1 is hidden in s2 if it is possible to find each character from s1 in s2, **in the same order as they appear in s1.**
If s1 is an empty `string`, it is considered hidden in any `string`.
If the number of arguments is different from 2, the program displays nothing.
- If `s1` is hidden in `s2`, the program should display `1` followed by a newline.
- If `s1` is not hidden in `s2`, the program should display `0` followed by a newline.
- If `s1` is an empty string, it is considered hidden in any string.
- If the number of arguments is different from 2, the program should display nothing.
