## hiddenp
|
|
|
|
|
|
|
|
|
|
### Instructions
|
|
|
|
|
|
|
|
|
|
Write a program named `hiddenp` that takes two `strings` 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.
|
|
|
|
|
|
|
|
|
|
Let s1 and s2 be `strings`. 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.
