## hiddenp
### Instructions
5 years ago
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.
5 years ago
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 parameters is different from 2, the program displays a newline.
